ARM: shmobile: KZM9D DT reference implementation 

Add a DT reference implementation for the KZM9D board.

Only DT devices are used in this case. UART, STI, GPIO
and SMP / GIC are all provided by emev2.dtsi.

There is still a board specific C file used for enabling
legacy SH clocks. This file will be removed after we have
moved over to common clocks.
