drm/etnaviv: add PE perf domain
We need to iterate over all pixel pipelines to get overall value. Changes from v4 -> v5: - switch back to pixel pipe 0 to prevent GPU hang - PIXELS_RENDERED_2D is exposed for 2D pipe Signed-off-by: Christian Gmeiner <christian.gmeiner@gmail.com> Signed-off-by: Lucas Stach <l.stach@pengutronix.de>
