Subject: [PATCH] cpuidle: tegra: honor ARCH_SUSPEND_POSSIBLE

When ARCH_SUSPEND_POSSIBLE is not enabled, selecting ARM_CPU_SUSPEND
causes a Kconfig warning, so make ARM_TEGRA_CPUIDLE depend on
ARCH_SUSPEND_POSSIBLE to prevent that warning.

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]

Fixes: 860fbde438dc ("cpuidle: Refactor and move out NVIDIA Tegra20 driver into drivers/cpuidle")
