ARMv8: Add basic PSCI framework
This patch introduces a generic ARMv8 PSCI framework, with all functions returning a dummy ARM_PSCI_RET_NI (Not Implemented), then it is up to each platform to implement their own functions based on this framework.

It is no problem to set a larger value than the number of CPUs in
the actual hardware implementation.

+ The number of CPUs per cluster, suppose each cluster has same number
+ of CPU cores, platforms with asymmetric clusters don't apply here.
+ A value 0 or no definition of it works for single cluster system.
+ System with multi-cluster should difine their own exact value.
