rapidio: add IDT CPS/TSI switches
Extentions to RapidIO switch support:
1. modify switch route operation declarations to allow using single
switch-specific file for family of switches that share the same route
table operations.
2. add standard route table operations for switches that that support
route table manipulation registers as defined in the Rev.1.3 of RapidIO
specification.
3. add clear-route-table operation for switches
4. add CPSxx and TSIxxx families of RapidIO switches
