[PATCH v3 1/3] etnaviv: sync uapi header

[Christian Gmeiner]

Import the etnaviv header changes from kernel commit 05916bed1 (drm-next)

The drm_etnaviv_gem_submit structure was extended to include performance
monitor requests. Also two new ioctls got added to be able to readout
performance monitor domains and their signals.
