ANDROID: Add vendor hook to the effective_cpu_util

Browse source 
android_rvh_effective_cpu_util:
	To perform vendor-specific cpu util, it is used in EAS/schedutil/thermal.

The effective_cpu_util would be called when thermal calc the dynamic power,
it's non-atomic context, so set the hook be restricted.
