radeonsi: clamp border colors for upgraded depth textures
The hardware does this automatically for unorm formats, but we need to
do it manually for unorm depth formats that have been upgraded to
Z32_FLOAT.
Fixes dEQP-GLES31.functional.texture.border_clamp.range_clamp.nearest_unorm_depth
and others.
Fixes: d4d9ec55c5 ("radeonsi: implement TC-compatible HTILE")
