FWIW, only AMDGPU_TILING_SET/GET need #undef,
AMDGPU_TILING_SWIZZLE_MODE_SHIFT/MASK and AMDGPU_FAMILY_AI can just be
#defined directly, that way the preprocessor will warn if the
definitions in libdrm and Mesa end up being inconsistent for some reason.


The alternative is rushing out a libdrm release and making Mesa require
that, right? That doesn't seem obviously better than a handful of
temporary redundant defines in Mesa, hardly justification for bypassing
the normal process.
