[Mesa-dev] [PATCH 07/18] i965/gen8: Use miptree format in the surface setup

[Topi Pohjolainen]

No functional change but this allows to drop the texture object's
mesa format in later patches.

Stencil buffer has fixed hardware format corresponding to fixed
mesa format. (This is in fact already specfically tested in
intel_fbo.c::intel_validate_framebuffer()).
