According to Hardware Programming Guide for DSI PHY, the retime buffer
resync should be done after PLL clock users (byte_clk and intf_byte_clk)
are enabled. Downstream also does it as part of configuring the PLL.
Driver was only turning off the resync FIFO buffer, but never bringing it
on again.

In the past %pK was preferable to %p as it would not leak raw pointer
values into the kernel log.
Since commit ad67b74d24 ("printk: hash addresses printed with %p")
the regular %p has been improved to avoid this issue.
Furthermore, restricted pointers ("%pK") were never meant to be used
through printk(). They can still unintentionally leak raw pointers or
acquire sleeping locks in atomic contexts.
Switch to the regular pointer formatting which is safer and

Currently, the high bitfield of certain DSI registers
do not align with the configuration of the SWI registers
description. This can lead to wrong programming these DSI
registers, for example for 4k resloution where H_TOTAL is
taking 13 bits but software is programming only 12 bits
because of the incorrect bitmask for H_TOTAL bitfeild,
this is causing DSI FIFO errors. To resolve this issue,
increase the high bitfield of the DSI registers from 12 bits
to 16 bits in dsi.xml to match the SWI register configuration.

To configure and enable the DSI PHY PLL clocks, the MDSS AHB clock must
be active for MMIO operations. Typically, this AHB clock is enabled as
part of the DSI PHY interface enabling (dsi_phy_enable_resource).
However, since these PLL clocks are registered as clock entities, they
can be enabled independently of the DSI PHY interface, leading to
enabling failures and subsequent warnings:
```
msm_dsi_phy 5e94400.phy: [drm:dsi_pll_14nm_vco_prepare] *ERROR* DSI PLL lock failed
------------[ cut here ]------------
dsi0pllbyte already disabled
WARNING: CPU: 3 PID: 1 at drivers/clk/clk.c:1194 clk_core_disable+0xa4/0xac

Hardware name: Qualcomm Technologies, Inc. Robotics RB1 (DT)
pstate: 600000c5 (nZCv daIF -PAN -UAO -TCO -DIT -SSBS BTYPE=--)
[...]
```
This issue is particularly prevalent at boot time during the disabling of
unused clocks (clk_disable_unused()) which includes enabling the parent
clock(s) when CLK_OPS_PARENT_ENABLE flag is set (this is the case for the
14nm DSI PHY PLL consumers).
To resolve this issue, we move the AHB clock as a PM dependency of the DSI
PHY device (via pm_clk). Since the DSI PHY device is the parent of the PLL
clocks, this resolves the PLL/AHB dependency. Now the AHB clock is enabled
prior the PLL clk_prepare callback, as part of the runtime-resume chain.
We also eliminate dsi_phy_[enable|disable]_resource functions, which are
superseded by runtime PM.
Note that it breaks compatibility with kernels before 6.0, as we do not
support anymore the legacy `iface_clk` name.
