We'd like to use cpuidle-arm.c for both arm and arm64 with psci as backend.
For arm64, it works. But for arm, we miss cpuidle_ops, these patches try to
address this issue.
Has been tested on Marvell Berlin SoCs. These patches are rebased on the Mark
Rutland's latest psci unification work and Lorenzo Pieralisi's psci related
work[1].
[PATCH 1/4] renames psci_smp.c to psci.c to prepare for the next two changes.
[PATCH 2/4] enables PSCI on UP systems
[PATCH 3/4] move psci's cpu_suspend handling to generic code as suggested
by Lorenzo.
[PATCH 4/4] implement cpuidle_ops with psci finally.
