drm/etnaviv: Allow DRAW_INSTANCED commands
Vivante GPUs with HALTI0 feature support a DRAW_INSTANCED command in the command stream to draw a number of instances of the same geometry. The information that has been figured out about the command can be found here: https://github.com/etnaviv/etna_viv/blob/master/rnndb/cmdstream.xml#L270 This command is not allowed currently by the DRM driver because it was not known before. This patch enables parsing it in command streams and allows using it by userspace drivers.
