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.
