[PATCH 11/13] rapidio: modify for rev.3 specification changes

From: Alexandre Bounine
Date: Thu Jul 21 2016 - 14:24:59 EST

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.
