Lucas Stach f232d9ec02 drm/etnaviv: fix TS cache flushing on GPUs with BLT engine
As seen in the Vivante kernel driver, most GPUs with the BLT engine have
a broken TS cache flush. The workaround is to temporarily set the BLT
command to CLEAR_IMAGE, without actually executing the clear. Apparently
this state change is enough to trigger the required TS cache flush. As
the BLT engine is completely asychronous, we also need a few more stall
states to synchronize the flush with the frontend.
