Alexandre Bounine a93192a5d2 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.

Alexandre Bounine 1548bf316f rapidio: fix destructive port EM initialization for Tsi568
Replace possibly damaging broadcast writes into the per-port SP_MODE
registers with individual writes for each port.  This will preserve
individual port configurations in case if ports are configured
differently.

Alexandre Bounine 058f88d672 rapidio: modify initialization of switch operations
Modify the way how RapidIO switch operations are declared.  Multiple
assignments through the linker script replaced by single initialization
call.

Alexandre Bounine 07590ff039 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
