3790ee07e6 v3d: Fix txf_ms 2D_ARRAY array index. 
We need to pass the array index through our coordinate transform
unchanged.  Fixes

e717e3e7cd broadcom/vc5: Add lowering for txf_ms to a txf on a 2x2-scaled texture. 
The HW has no native sampler support for multisample textures, but since
we only need to support txf_ms and the layout is UIF, we just need to
scale up the texcoords and then add in the sample.

This drops the old TEXTURE_MSAA_ADDR special uniform, since we're treating
MSAA textures as textures, rather than basically texbos like VC4 had to.
