Lucas Stach 2cc97daab5 drm/etnaviv: hold GPU lock across perfmon sampling 
[ 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.

Fixes: 68dc0b295d ("drm/etnaviv: use 'sync points' for performance monitor requests")
