Added S4 audio tocodec binding support.

2 Driver Implementation
Implemented S4 tocodec driver for G12A architecture.
Added S4 audio clock support in AXG audio clock 

3 Device Tree Integration

Jiebing,

FYI

I applied this series over 6.18.7 and tested on s905w2 device.

With audio routing like this:

amixer cset numid=40,iface=MIXER,name='FRDDR_A SINK 1 SEL' 0
amixer cset numid=73,iface=MIXER,name='TDMOUT_A SRC SEL' 0
amixer cset numid=37,iface=MIXER,name='FRDDR_A SRC 1 EN Switch' 1
amixer cset numid=61,iface=MIXER,name='TOACODEC SRC' 0
amixer cset numid=1,iface=MIXER,name='TOACODEC Lane Select' 0
amixer cset numid=62,iface=MIXER,name='TOACODEC OUT EN Switch' 1
amixer cset numid=17,iface=MIXER,name='ACODEC Playback Volume' 251 251

i'm getting working audio on analog headset.

Great work!

My bot found new DTB warnings on the .dts files added or changed in this
series.

Some warnings may be from an existing SoC .dtsi. Or perhaps the warnings
are fixed by another series. Ultimately, it is up to the platform
maintainer whether these warnings are acceptable or not. No need to reply
unless the platform maintainer has comments.

If you already ran DT checks and didn't see these error(s), then
make sure dt-schema is up to date:

  pip3 install dtschema --upgrade


This patch series was applied (using b4) to base:
 Base: a0c666c25aeefd16f4b088c6549a6fb6b65a8a1d (use --merge-base to override)

If this is not the correct base, please add 'base-commit' tag
(or use b4 which does this automatically)
