freedreno: remove flush queue

Rob Clark requested to merge robclark/mesa:wip/remove-flush-queue into master

In the end I still needed a big lock around render_tiles(), so I suppose splitting out and caching the GMEM state wasn't strictly needed. But it was kinda a thing I'd wanted to do for a while.

This seems to help keep the GPU utilization during manhattan (mostly) at 100%. I suspect with the async flush-queue we were probably hitting some lock contention (struct_mutex on kernel side, between SUBMIT ioctl and MADVISE and/or allocation?)
