Lucas Stach c737219c86 drm/etnaviv: hold GPU lock across perfmon sampling ...

[ Upstream commit 37dc473744 ]

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.
