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.

In order to perform timestamps correlation for FECS
traces, we need to collect GPU / GPU timestamps
samples. In virtualization case, it is possible for
a guest to get GPU timestamps by using read_ptimer.
However, if the CPU timestamp is read on guest side,
and the GPU timestamp is read on vm-server side,
then it introduces some latency that will create an
artificial offset for GPU timestamps (~2 us in
average). For better CPU / GPU timestamps correlation,
Added a command to collect all timestamps on vm-server
side.
