drm/msm/gpu: Respect PM QoS constraints
Re-work the boost and idle clamping to use PM QoS requests instead, so
they get aggreggated with other requests (such as cooling device).
This does have the minor side-effect that devfreq sysfs min_freq/
max_freq files now reflect the boost and idle clamping, as they show
(despite what they are documented to show) the aggregated min/max freq.
Fixing that in devfreq does not look straightforward after considering
that OPPs can be dynamically added/removed. However writes to the
sysfs files still behave as expected.
v2: Use 64b math to avoid potential 32b overflow
