Currently callbacks from the PM_QOS framework (for
thermal events), result in a RPC call to set GPU frequency.
Since the governor will now be responsible for setting desired
rate, the max PM_QOS callback will now cap the possible
GPU frequency w/ a new RPC call to the server. The server
is responsible for setting the ultimate frequency
based on the cap & desired rates.
