Liu Gang - June 25, 2013, 10:12 a.m.
For some PowerPC platforms, LIODN registers for SRIO ports are
in SRIO register address space. So the ccsr_rio structure should
be updated for those LIODN registers.

In addition, add a new macro "SET_SRIO_LIODN_BASE" to create
the SRIO LIODN ID table based on the SRIO LIODN register address.
