[ Upstream commit 37dc4737447a7667f8e9ec790dac251da057eb27 ]
The perfmon sampling mutates shared GPU state (e.g. VIVS_HI_CLOCK_CONTROL
to select the pipe for the perf counter reads). To avoid clashing with
other functions mutating the same state (e.g. etnaviv_gpu_update_clock)
the perfmon sampling needs to hold the GPU lock.
