ARM: 5786/1: Introduce plat-nomadik, MTU code re-organization

Introduce the plat-nomadik folder for ST-Ericsson
machines including the existing nomadik 8815 architecture.
This also moves the existing MTU (MultiTimerUnit)
of nomadik 8815 to the proposed plat-nomadik and adds
HAS_MTU. The patch has been re-based to 2.6.32-rc6
