i965/gen6 depth surface: program 3DSTATE_DEPTH_BUFFER to top of surface
(bf25ee2 for gen6)
Previously we would always find the 2D sub-surface of interest,
and then program the surface to this location. Now we always
program the 3DSTATE_DEPTH_BUFFER at the start of the surface.
To select the lod/slice, we utilize the lod & minimum array
element fields.
We also must disable brw_workaround_depthstencil_alignment for
gen >= 6. Now the hardware will handle alignment when rendering
to additional slices/LODs.
v3:
* Set depth_mt bo RELOC offset to 0, as was done in bf25ee2
