sched: Add CONFIG_SCHED_HMP Kconfig option
Add a compile-time flag to enable or disable scheduler features for
HMP (heterogenous multi-processor) systems. Main feature deals with
optimizing task placement for best power/performance tradeoff.
Also extend features currently dependent on CONFIG_SCHED_FREQ_INPUT to
be enabled for CONFIG_HMP as well.
