radeonsi: Assorted depth/stencil changes ported from r600g.
[ Squashed port of the following r600g commits: - Michel Dänzer ] commitc1e8c845ea
Author: Marek Olšák <maraeo@gmail.com> Date: Sat Jul 7 19:10:00 2012 +0200 r600g: inline r600_hw_copy_region commit4891c5dc64
Author: Marek Olšák <maraeo@gmail.com> Date: Mon Jun 25 22:53:21 2012 +0200 r600g: inline r600_blit_push_depth and use resource_copy_region We are going to have a separate resource for depth texturing and transfers and this is just a transfer thing. commitda98bb6fc1
