rapidio: modify for rev.3 specification changes

Implement changes made in RapidIO specification rev.3 to LP-Serial Physical
Layer register definitions:

 - use per-port register offset calculations based on LP-Serial Extended
   Features Block (EFB) Register Map type (I or II) with different
   per-port offset step (0x20 vs 0x40 respectfully).

 - remove deprecated Parallel Physical layer definitions and related
   code.
