TAS2764 contains an ADC that reports the chip's die temperature.
The temperature in degrees Celsius is yielded by subtracting 93
from the raw value reported by the ADC.
Expose the codec die temperature to the hwmon interface.
The chip will initialise the temperature register to 2.6 *C
to avoid triggering over temp protection. As the ADC is powered
down during software shutdown, this value will persist until the
chip is fully powered up (e.g. when the PCM it's attached to is
opened). When the chip is powered back down, the last value sampled
will persist in the register.

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.

TX launch polarity needs to be the opposite of RX capture polarity, to
generate the right bit slot alignment.

Add an IRQ handler which logs detected faults (but doesn't do anything

Fix setting of FSYNC polarity in case of LEFT_J and DSP_A/B formats.
Do NOT set the SCFG field as was previously done, because that is not
correct and is also in conflict with the "ASI1 Source" control which
sets the same SCFG field!
Also add support for explicit polarity inversion.
