[PATCH 0/2] uclamp_max vs schedutil fixes

[Qais Yousef]

On systems that use sugov_update_single_{freq, perf}(), uclamp_max was
ineffective because of 'busy' filter which ignores requests to change frequency
if there's no idle time. A condition that is not true if uclamp is being used
on this system.

Similarly, io heavy tasks that are capped by uclamp_max can still obtain higher
frequencies because sugov_iowait_apply() doesn't clamp the boost with
uclamp_rq_util_with().

Patches 1 and 2 address these 2 problems.

Thanks!
