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.
