[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]
