rapidio: fix default routing initialization
...
Fix switch initialization to ensure that all switches have default routing
disabled. This guarantees that no unexpected RapidIO packets arrive to
the default port set by reset and there is no default routing destination
until it is properly configured by software.
This update also unifies handling of unmapped destinations by tsi57x, IDT
Gen1 and IDT Gen2 switches.

rapidio: use common destid storage for endpoints and switches
...
Change code to use one storage location common for switches and endpoints.
This eliminates unnecessary device type checks during basic access
operations. Logic that assigns destid to RIO devices stays unchanged - as
before, switches use an associated destid because they do not have their
own.

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
