At very early stage on boot, there is a need to set 'mips_hpt_frequency'.
This timer frequency is a half of the CPU frequency. To get clocks properly
set we need to call to 'of_clk_init()' and properly get cpu clock frequency
afterwards. Depending on the SoC, CPU clock index and compatible differs, so
use them to get the proper clock frm the clock provider. Hence, adapt code
to be aligned with new clock driver.

A proper clock driver for ralink SoCs has been added. This driver is also
a reset provider for the SoC. Hence there is no need to have reset related
code in 'arch/mips/ralink' folder anymore. The only code that remains is
the one related with mips_reboot_setup where a PCI reset is performed.
We maintain this because I cannot test old ralink board with PCI to be
sure all works if we remove also this code.

Until now, clock related code for old ralink SoCs was based in fixed clocks
using 'clk_register_fixed_rate' and 'clkdev_create' directly doing in code
and not using device tree at all for their definition. Including this driver
is an effort to be able to define proper clocks using device tree and also
cleaning all the clock and reset related code from 'arch/mips/ralink' dir.
This clock and reset driver covers all the ralink SoCs but MT7621 which is
the newest and provides gating and some differences that make it different
from its predecesors. It has its own driver since some time ago. The ralink
SoCs we are taking about are RT2880, RT3050, RT3052, RT3350, RT3352, RT3883,
RT5350, MT7620, MT7628 and MT7688. Mostly the code in this new driver has
been extracted from 'arch/mips/ralink' and cleanly put using kernel clock
driver APIs. The clock plans for this SoCs only talks about relation between
CPU frequency and BUS frequency. This relation is different depending on the
particular SoC. CPU clock is derived from XTAL frequencies.
Depending on the SoC we have the following frequencies:
* RT2880 SoC:
- XTAL: 40 MHz.
- CPU: 250, 266, 280 or 300 MHz.
- BUS: CPU / 2 MHz.
* RT3050, RT3052, RT3350:
- XTAL: 40 MHz.
- CPU: 320 or 384 MHz.
- BUS: CPU / 3 MHz.
* RT3352:
- XTAL: 40 MHz.
- CPU: 384 or 400 MHz.
- BUS: CPU / 3 MHz.
- PERIPH: 40 MHz.
* RT3383:
- XTAL: 40 MHz.
- CPU: 250, 384, 480 or 500 MHz.
- BUS: Depends on RAM Type and CPU:
+ RAM DDR2: 125. ELSE 83 MHz.
+ RAM DDR2: 128. ELSE 96 MHz.
+ RAM DDR2: 160. ELSE 120 MHz.
+ RAM DDR2: 166. ELSE 125 MHz.
* RT5350:
- XTAL: 40 MHz.
- CPU: 300, 320 or 360 MHz.
- BUS: CPU / 3, CPU / 4, CPU / 3 MHz.
- PERIPH: 40 MHz.
* MT7628 and MT7688:
- XTAL: 20 MHz or 40 MHz.
- CPU: 575 or 580 MHz.
- BUS: CPU / 3.
- PCMI2S: 480 MHz.
- PERIPH: 40 MHz.
* MT7620:
- XTAL: 20 MHz or 40 MHz.
- PLL: XTAL, 480, 600 MHz.
- CPU: depends on PLL and some mult and dividers.
- BUS: depends on PLL and some mult and dividers.
- PERIPH: 40 or XTAL MHz.
MT7620 is a bit more complex deriving CPU clock from a PLL and an bunch of
register reads and predividers. To derive CPU and BUS frequencies in the
MT7620 SoC 'mt7620_calc_rate()' helper is used.
In the case XTAL can have different frequencies and we need a different
clock frequency for peripherals 'periph' clock in introduced.
The rest of the peripherals present in the SoC just follow their parent
frequencies.
With this information the clk driver will provide all the clock and reset
functionality from a set of hardcoded clocks allowing to define a nice
device tree without fixed clocks.

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.
To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new() which already returns void. Eventually after all drivers
are converted, .remove_new() is renamed to .remove().
Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.
While destroying alignment of the assignments in bridge_driver, do it
consistently and use a single space before =.

After commit 96cb8ae28c ("MIPS: Rework smt cmdline parameters"),
modpost complains when building with clang:
WARNING: modpost: vmlinux.o: section mismatch in reference: core_vpe_count (section: .text) -> smp_max_threads (section: .init.data)
This warning occurs when core_vpe_count() is not inlined, as it appears
that a non-init function is referring to an init symbol. However, this
is not a problem in practice because core_vpe_count() is only called
from __init functions, cps_smp_setup() and cps_prepare_cpus().
Resolve the warning by marking core_vpe_count() as __init, as it is only
called in an init context so it can refer to init functions and symbols
and have its memory freed on boot.

Wire the WiFi/Bluetooth chip properly in the Device Tree.
- Provide it with the correct regulators and clocks;

- Change the MMC I/O bus frequency to 25 MHz as 50 MHz causes errors;
- Fix the Bluetooth powerdown GPIO being inverted and add reset GPIO;
- Convert host-wakeup-gpios to IRQ.
With these changes, the WiFi works properly with the latest firmware

The Device Tree was using invalid node names for the ACT8600 regulators.
To be fair, it is not the original committer's fault, as the
documentation did gives invalid names as well.
In theory, the fix should have been to modify the driver to accept the
alternative names. However, even though the act8865 driver spits
warnings, the kernel seemed to work fine with what is currently
supported upstream. For that reason, I think it is okay to just update
the DTS.
I removed the "regulator-name" too, since they really didn't bring any

The JZ4750, JZ4755 and JZ4760 (non-B version) support using a 24 MHz
external crystal oscillator instead of the typical 12 MHz one.
However, most of the SoC's IP blocks only work with a 12 MHz clock.
Thanksfully, there is a /2 divider we can enable when a 24 MHz external
crystal is present.
Force-enable this /2 divider when the oscillator is 24 MHz, so that the
SoC always uses a 12 MHz clock internally.
It is done here, and not in the clocks driver, because we need the EXT
clock to be 12 MHz for the early console to work, and the clocks driver
probes way too late.
