Any of the following devices connected to I2C ch4 of the Salvator-X(S)
boards will operate at 400 kHz:
PCA9654, 9FGV0841, ADV7482WBBCZ, MAX9611, 5P49V5923, 5P49V6901A
This patch updates the clock frequency to 400 KHz.

The Renesas Salvator-X and Salvator-XS (Salvator-X 2nd version) boards
are very similar. To avoid duplication, prepare for the advent of the
latter by extracting the common board parts into its own .dtsi file.

R-Car Gen3 SoCs contain multiple PWM modules. Hence to avoid conflicts,
pinctrl subnodes for PWM should include indices referring to their
instances.

Current rcar_sound only has 11289600 (= for 44.1kHz) clock-frequency,
but it needs 12288000 for 48kHz too.
Otherwise, 48kHz based sound can't handle correctly.

The Salvator-X board has two HDMI output connectors. Add them to the
common salvator-x.dtsi.

The DU1 and DU2 external dot clocks are fixed frequency clock generators
running at 33MHz, while the DU0 and DU3 external dot clocks are
generated by an I2C-controlled programmable clock generator.
All those clock generators are available on both the H3 and M3-W
Salvator-X boards. Add them to the salvator-x.dtsi file.

The Renesas Salvator-X development board can be equipped with either an
R-Car H3 or M3-W SiP, which are pin-compatible. Both boards use
different DTBs.
Reduce duplication by extracting common Salvator-X board support into
its own .dtsi file. References to SoC-specific clocks are handled
through cpp definitions. Sort device nodes while at it.
For boards with an R-Car H3 SiP, there are no functional changes.
For boards with an R-Car M3-W SiP, the following new devices are now
described in DT:
- External audio, CAN, and PCIe clocks,
- USB Vbus regulator,
- CS2000 clock generator,
- AK4613 Audio Codec,
- VGA.
