The Audio Codec runs over the MCASP (Multichannel Audio Serial Port).
Add pinmux for the Audio Reference Clock and MCASP2.
Add DT nodes for Audio Codec, MCASP2, VCC 1v8 and VCC 3v3 regulators.
Additionally, create a sound node that connects our sound card and the
MCASP2.

I have applied the following to branch ti-k3-dts-next on [1].
Thank you!
[1/1] arm64: dts: ti: k3-am625-phyboard-lyra-rdk: Add Audio Codec
commit: 641eb61369bb27e4fec76f311aef58e3572d2147
All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent up the chain during
the next merge window (or sooner if it is a relevant bug fix), however if
problems are discovered then the patch may be dropped or reverted.
You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.
If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.
Please add any relevant lists and maintainers to the CCs when replying
to this mail.
