mainboard/google/hatch: Remove MAX98357A assumption from baseboard
Generally work towards a more loose baseboard definition by moving out
some original assumptions to be board specifics. Specifically Puff does
not have the MAX98357A speaker amp and enabling the driver winds up
generating incorrect SSDT tables that confuse the kernel. Since
devicetree inherits the chip from device node in base and an override
will also inherit the chip and thus dispatch the unwanted fill_ssdt fn
call.
V.2: lean on linker to drop max98357a driver when not in dt.
