feat(3p/kernelPatches): Add kernel audio patch for ASUS TRX40 Pro

Without this patch, this board is not included in the pin map
overrides and audio basically doesn't work.

With this patch, the audio still doesn't work, but it can at least
correctly detect what is and isn't plugged in - so that's progress.
