====================
first series for xpcs based rsfec configuration

The series:
- Fixes an addr validation error
- Adds MDIO defines associated with RS-FEC
- consolidates the handling of the boilerplat ID registers
  into a routine to report id'ish registers and reduces the lines
  of code across the entire set of c45 routines.
- adds PMA read/write routines
