rapidio: add architecture specific callbacks

Browse Source 
This set of patches eliminates RapidIO dependency on PowerPC architecture
and makes it available to other architectures (x86 and MIPS).  It also
enables support of new platform independent RapidIO controllers such as
PCI-to-SRIO and PCI Express-to-SRIO.

This patch:

Extend number of mport callback functions to eliminate direct linking of
architecture specific mport operations.
