r600g,radeonsi: force fast stencil and HTILE stencil off, fixing a Hyper-Z hang
This should be as fast as no HTILE for stencil. I think we can still get full
performance with depth-only rendering even if stencil is present in the buffer
but not used, but I'm not 100% sure. This may be revisited when HiS and fast
stencil clear are implemented.
This fixes a hang in Brutal Legend.
