ARM: shmobile: ARCH_MULTIPLATFORM for EMEV2 and KZM9D

[PATCH 01/04] ARM: shmobile: Only build clocks when COMMON_CLK=n [PATCH 02/04] ARM: shmobile: Introduce ARCH_SHMOBILE_MULTI [PATCH 03/04] ARM: shmobile: Add EMEV2 and KZM9D to ARCH_SHMOBILE_MULTI [PATCH 04/04] ARM: shmobile: Allow ARCH_SHMOBILE_MULTI timer configuration

This patch set extends mach-shmobile to allow a subset of SoCs and boards to be built for ARCH_MULTIPLATFORM. With this series applied the EMEV2 SoC and the KZM9D board can be built in two ways - either as good old ARCH_SHMOBILE or new ARCH_SHMOBILE_MULTI. The latter requires common clock framework for proper run time operation.

The goal is to over time move all DT reference implementations from ARCH_SHMOBILE to ARCH_SHMOBILE_MULTI. Until CCF is available for a certain SoC it is to me acceptable for a DT reference board to allow build in both ARCH_SHMOBILE and ARCH_SHMOBILE_MULTI. The reason for this is to allow incremental development and easy testing during development of CCF for a certain SoC. The KZM9D board is now in this state while it is waiting for common clocks to become ready.

In the near future a prototype hack will be posted that comments out the clock framework bits on EMEV2 and will allow boot of KZM9D in the case of ARCH_SHMOBILE_MULTI even though CCF is not yet available.
