freedreno/a4xx: better workaround for astc+srgb
This *seems* like a hw bug, and maybe only applies to certain a4xx
variants/revisions. But setting the SRGB bit in sampler view state
(texconst0) causes invalid alpha for ASTC textures. Work around this
setting up a second texture state and using that to sample alpha
separately.
This way, srgb->linear conversion happens in hw *prior* to
interpolation.
This fixes 546 dEQP tests: dEQP-GLES3.functional.texture.*astc*srgb*
