mb/google/mancomb: Enable AMD I2S Machine Driver
Enable AMD I2S machine driver and configure the devicetree with HID

kernel. Also configure Audio Co-processor(ACP) to operate in I2S TDM mode.
BUG=b:187860242
TEST=Build and boot to OS in Guybrush. Ensure that the ACPD device is
enabled in the appropriate scope in SSDT.
