This adds a few things to try and make frequency scaling better match
the workload:
1) Longer polling interval to avoid whip-lashing between too-high and
too-low frequencies in certain workloads, like mobile games which
throttle themselves to 30fps.

In the next patch, it grows a bit more, so lets not duplicate the logic

This is the outcome of trying to fix some bad gpu freq behavior seen in
some use-cases, in particular mobile games that throttle themselves to
30fps. With the existing tuning, we'd end up spending most of the time
that we should be running fast at a low freq, and most of the
There is a scenario that dp cable is unplugged from DUT during system
suspended will cause audio option state does not match real connection
state. Fix this problem by Signaling audio plugged change with realtime
connection status at dp_pm_resume() so that audio option will be in
correct state
