refactor(drivers/marvell/comphy-3700): drop _ADDR suffixes

COMPHY register addresses are defined twice
- once for indirect access, where the constants are of the form
  COMPHY_<register_name>
- once for direct access, with constants of the form
  <register_name>_ADDR

But sometimes the first case also has this _ADDR suffix (and other times
not).

Drop it from those places to unify how we define these registers.
