[ Upstream commit ad18392962df46a858432839cc6bcaf2ede7cc86 ]
SN012776 is a speaker amp chip found in Apple's 2021 laptops. It appears similar and more-or-less compatible to TAS2764. Extend the TAS2764 driver with some SN012776 specifics and configure the chip assuming it's in one of the Apple machines.
