[PATCH 08/08] mach-shmobile: Use DT_MACHINE for KZM9D V3

Wed May 16 02:46:03 EDT 2012
From: Magnus Damm <damm at opensource.se>
Use DT_MACHINE_START() on the emev2 based KZM9D board.
Also include a tiny DTS file to describe the board and
update the Kconfig dependencies to select CONFIG_USE_OF.
Update the SMP glue code to use OF for matching.
