r300g: implement hyper-z support. (v4)
This implements fast Z clear, Z compression, and HiZ support for r300->r500 GPUs. It also allows cbzb clears when fast Z clears are being used for the ZB. It requires a kernel with hyper-z support. Thanks to Marek Olšák <maraeo@gmail.com>, who started this off, and Alex Deucher at AMD for providing lots of hints. v2: squashed zmask ram size fix] squashed r300g/blitter: fix Z readback when compressed] v3: rebase around texture changes in master - .1 fix more bits v4: migrated to using u_mm in r300_texture to manage hiz/zmask rams consistently disabled HiZ when using OQ flush z-cache before turning hyper-z off update hyper-z state on dsa state change store depthclearvalue across cbzb clears and replace it afterwards.
