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]

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

I found this in my backlog of patches that never made it upstream, testing shows this is still needed. Please apply.
