gpu: nvgpu: gv11b: Support Stencil ZBC
Pre-GP10X
All chips prior to GP10X do not support ZBC (Zero Bandwidth Clear) to stencil
part of the packed kinds (packed kinds refer to Z24S8 and Z32_X24S8 kinds).
Clears for these kinds typically happen in two phases, depth phase and
stencil phase. The depth clears can be compressed or ZBC-ed, whereas the
stencil part is always uncompressed.
Stencil ZBC in GP10X
For GP10X both the depth and the stencil data for these packed kinds can be
ZBC cleared. A given tile will be a cross product of the following states
for depth and stencil.
Depth: Uncompressed, 1-2 plane compressed, 3-4 plane compressed, ZBC index 0,
ZBC index 1
Stencil: Uncompressed, ZBC index 0, ZBC index 1, ZBC index 2
