Should this patch also make shmobile_enter_wfi static in
arch/arm/mach-shmobile/cpuidle.c ?

Also, I have a slight preference for the patch to be split into two.
1. A patch to remove usage of shmobile_enter_wfi from the sh7372 SoC.
2. A patch to remove shmobile_enter_wfi. from common.h
   (and make it static?).
