sched/fair: introduce an arch scaling function for max frequency capping
The max frequency scaling factor is defined as:
max_freq_scale = policy_max_freq / cpuinfo_max_freq
To be able to scale the cpu capacity by this factor introduce a call to
the new arch scaling function arch_scale_max_freq_capacity() in
update_cpu_capacity() and provide a default implementation which returns
SCHED_CAPACITY_SCALE.
Another subsystem (e.g. cpufreq) can overwrite this default implementation,
exactly as for frequency and cpu invariance. It has to be enabled by the
arch by defining arch_scale_max_freq_capacity to the actual
implementation.
