Renesas ARM based SoC multiplatform updates for v3.12

Move Renesas ARM based SoCs a little closer to using
multiplatform by adding ARCH_SHMOBILE_MULTI and only
building clocks when COMMON_CLK=n.

* tag 'renesas-multiplatform-for-v3.12' of git://git.kernel.org/pub/scm/linux/kernel/git/horms/renesas:
  ARM: shmobile: Allow ARCH_SHMOBILE_MULTI timer configuration
  ARM: shmobile: Add EMEV2 and KZM9D to ARCH_SHMOBILE_MULTI
  ARM: shmobile: Introduce ARCH_SHMOBILE_MULTI
  ARM: shmobile: Only build clocks when COMMON_CLK=n
