The i.MX USB Phy driver does not check register ranges, resulting in out of
bounds accesses if an attempt is made to access non-existing PHY registers.
Add range check and conditionally report bad accesses to fix the problem.
While at it, also conditionally log attempted writes to non-existing or
read-only registers.
