The problem with hard coding them is you need some way to know which
set of hard coded values to use, because the hardware engineers will
not guarantee to never move them, or change the bit layout for the
next generation of devices.

PHYs don't use compatibles because they have an ID in register 2 and
3. Is this ID specific to the MT7988?
