arm64: Cpu invariant scheduler load-tracking and capacity support
Provides the scheduler with a cpu scaling correction factor for more
accurate load-tracking and cpu capacity handling.
The Energy Model (EM) (in fact the capacity value of the last element
of the capacity states vector of the core (MC) level sched_group_energy
structure) is used as the source for this cpu scaling factor.
The cpu capacity value depends on the micro-architecture and the
maximum frequency of the cpu.
The maximum frequency part should not be confused with the frequency
invariant scheduler load-tracking support which deals with frequency
related scaling due to DFVS functionality.
