This patch adds LVDS support on stm32mp255. The LVDS is used on
STM32MP2 as a display interface. LVDS PLL clock is binded to the LTDC
input clock.

In RCC driver, 'DSI_K' is a kernel clock while 'DSI' has pclk4 as parent
clock, which means that it is an APB peripheral clock. Swap the clocks
in the DSI peripheral clock reference.

Use RUNTIME_PM_OPS() instead of the old SET_SYSTEM_SLEEP_PM_OPS().
This means we don't need __maybe_unused on the functions.

Changes in v2:
- Changed SET_RUNTIME_PM_OPS to RUNTIME_PM_OPS and removed
phy' is not implemented. Since the
DSI kernel clock is based on the internal DSI pll. The common clock
driver can not directly expose this 'ck_dsi_phy' clock because it does
not contain any common registers with the DSI. Thus it needs to be done
directly within the DSI phy driver.
