Subject: [PATCH 1/2] cpuidle: cpuidle-arm: remove arm64 support

Since commit 788961462f34 ("ARM: psci: cpuidle: Enable PSCI CPUidle
driver") the generic ARM cpuidle driver doesn't probe anymore because
arm_cpuidle_init() will always return -EOPNOTSUPP. That is, because the
mentioned commit removes the only .cpu_suspend and .cpu_init_idle
provider.
