[PATCH 4/5 v2] Add RapidIO support to powerpc architecture.
This patch adds the RapidIO support to the powerpc architecture.
Some files are moved from ppc. OF-tree and OF-device supports are added.
New silicons such as MPC8548, MPC8641 with serial RapidIO controller are
all supported.
Memory driver hardware operations are added.
Global mport variables are changed to master port private variables.
Multi master ports are supported.
