ARM: cpuidle: Enable the ARM64 driver for both ARM32/ARM64

Browse Source 
ARM32 and ARM64 have the same DT definitions and the same approaches.

The generic ARM cpuidle driver can be put in common for those two
architectures.

Select this to enable generic cpuidle driver for ARM.
It provides a generic idle driver whose idle states are configured
at run-time through DT nodes. The CPUidle suspend backend is
initialized by calling the CPU operations init idle hook
provided by architecture code.
