The device tree updates ensure the A53 don't get powered off and fix a
DT warning. This isn't testable with the arm64 default config unless we
enable the rsi wifi modules too so do this as well.

While at that include two binding file updates.

This is against next-20230809 that include David's option,gtm601
conversion.

Hi Guido,

Normally we should use vmmc-supply to control the M.2 pin56(W_DISABLE1#), which controls the WLAN radio power.
And use the reset-gpios of mmc-pwrseq to control the M.2 pin23(SDIO_RESET#), it can independently reset the Wi-Fi radio.

Best Regards
Sherry

Makes little odds IMO which way it is done.

Thanks!

[1/5] dt-bindings: sound: gtm601: Add description
      commit: 6870f41033d839fa72195fd2dd37f902b37ea62b

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a 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.

Thanks,
Mark
