radeonsi: fix DCC fast clear for luminance and alpha formats
I reproduced this bug on Polaris11 and Raven. I can't get this bug on Fiji. The reason might be that Fiji doesn't use 2D tiling for the test due to higher 2D tiling alignment requirements. Fixes piglit: spec@ext_framebuffer_object@fbo-fast-clear Reviewed-by: Nicolai Hähnle <[email protected]>
