cpuidle: add ARCH_SUSPEND_POSSIBLE dependencies

cpuidle: add ARCH_SUSPEND_POSSIBLE dependencies

Some ARMv4 processors don't support suspend, which leads
to a build failure with the tegra and qualcomm cpuidle driver:

WARNING: unmet direct dependencies detected for ARM_CPU_SUSPEND
  Depends on [n]: ARCH_SUSPEND_POSSIBLE [=n]
  Selected by [y]:
  - ARM_TEGRA_CPUIDLE [=y] && CPU_IDLE [=y] && (ARM [=y] || ARM64) && (ARCH_TEGRA [=n] || COMPILE_TEST [=y]) && !ARM64 && MMU [=y]

arch/arm/kernel/sleep.o: in function `__cpu_suspend':
(.text+0x68): undefined reference to `cpu_sa110_suspend_size'
(.text+0x68): undefined reference to `cpu_fa526_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")
