The PowerVR IP does not contain display hardware - this means it is always necessary to open two separate devices for render and display. The try_create_for_drm callback is not suitable for this configuration, so we use the enumerate callback instead. The previous implementation did not check that the discovered display device was compatible with the render device - this is corrected by unifying the compatibility lists into pvr_drm_configs. The pvr driver is not currently supported on systems which contain multiple compatible render or display devices, so the enumerate callback implementation returns the first discovered render device and its compatible display device. This change also removes the workaround for drmGetDevices2() required after libdrm commit 8cb12a2528d795c45bba5f03b3486b4040fb0f45. The upstream fix has been in releases of libdrm for over a year now, and mesa requires reasonably a recent version which is new enough to contain it.
