ARM: shmobile: Take cpuidle dependencies into account correctly
The sh7372's cpuidle code uses cpu_suspend() and cpu_resume() in
its implementation of the .enter() callback for deeper C-states, so
make ARCH_SH7372 select ARM_CPU_SUSPEND if CPU_IDLE is set to satisfy
all of the build dependencies (it has to be selected for CONFIG_PM
as well for the system suspend handling).
