[ARM] 3590/1: AT91RM9200 Platform devices support 



Patch from Andrew Victor

This patch includes the structures and exported functions required for
the platform-device support (added in patch 3585/1).

Also adds the arch_identify() function for run-time detection of which
AT91 processor the code is running on.  [Original patch from Ivan
Kokshaysky]
