dt-bindings: clock: Convert marvell,armada-3700-periph-clock to DT schema

Browse Source 
Convert the Marvell Armada 3700 peripheral clock binding to DT schema
format. The north bridge is also a "syscon", so add the compatible to
it.

* Peripheral Clock bindings for Marvell Armada 37xx SoCs
Marvell Armada 37xx SoCs provide peripheral clocks which are
used as clock source for the peripheral of the SoC.
There are two different blocks associated to north bridge and south
bridge.
The peripheral clock consumer should specify the desired clock by
having the clock ID in its "clocks" phandle cell.
The following is a list of provided IDs for Armada 3700 North bridge clocks:
ID Clock name Description
-----------------------------------
0 mmc MMC controller
1 sata_host Sata Host
2 sec_at Security AT
3 sac_dap Security DAP
4 tsecm Security Engine
5 setm_tmx Serial Embedded Trace Module
6 avs Adaptive Voltage Scaling
7 sqf SPI
8 pwm PWM
9 i2c_2 I2C 2
10 i2c_1 I2C 1
11 ddr_phy DDR PHY
12 ddr_fclk DDR F clock
13 trace Trace
14 counter Counter
15 eip97 EIP 97
16 cpu CPU
The following is a list of provided IDs for Armada 3700 South bridge clocks:
ID Clock name Description
-----------------------------------
0 gbe-50 50 MHz parent clock for Gigabit Ethernet
1 gbe-core parent clock for Gigabit Ethernet core
2 gbe-125 125 MHz parent clock for Gigabit Ethernet
3 gbe1-50 50 MHz clock for Gigabit Ethernet port 1
4 gbe0-50 50 MHz clock for Gigabit Ethernet port 0
5 gbe1-125 125 MHz clock for Gigabit Ethernet port 1
6 gbe0-125 125 MHz clock for Gigabit Ethernet port 0
7 gbe1-core Gigabit Ethernet core port 1
8 gbe0-core Gigabit Ethernet core port 0
9 gbe-bm Gigabit Ethernet Buffer Manager
10 sdio SDIO
11 usb32-sub2-sys USB 2 clock
12 usb32-ss-sys USB 3 clock
13 pcie PCIe controller
Required properties:
- compatible : shall be "marvell,armada-3700-periph-clock-nb" for the
north bridge block, or
"marvell,armada-3700-periph-clock-sb" for the south bridge block
- reg : must be the register address of North/South Bridge Clock register
- #clock-cells : from common clock binding; shall be set to 1
- clocks : list of the parent clock phandle in the following order:
TBG-A P, TBG-B P, TBG-A S, TBG-B S and finally the xtal clock.
Example:
nb_perih_clk: nb-periph-clk@13000{
compatible = "marvell,armada-3700-periph-clock-nb";
reg = <0x13000 0x1000>;
clocks = <&tbg 0>, <&tbg 1>, <&tbg 2>,
<&tbg 3>, <&xtalclk>;
#clock-cells = <1>;
};
