From: Arnd Bergmann <arnd@arndb.de>

Some StrongARM processors don't support suspend, which leads
to a build failure with the tegra cpuidle driver:

WARNING: unmet direct dependencies detected for ARM_CPU_SUSPEND
  Depends on [n]: ARCH_SUSPEND_POSSIBLE [=n]
  Selected by [y]:
  - ARM_QCOM_SPM_CPUIDLE [=y] && ...

arch/arm/kernel/sleep.o: in function `__cpu_suspend':
(.text+0x68): undefined reference to `cpu_sa110_suspend_size'

Add an explicit dependency to make randconfig builds avoid
this combination.

Fixes: a871be6b8eee ("cpuidle: Convert Qualcomm SPM driver to a generic CPUidle driver")
