radeonsi: fix texture format reinterpretation with DCC
DCC is limited in how texture formats can be reinterpreted using texture
views. If we get a view format that is incompatible with the initial
texture format with respect to DCC, disable DCC.
There is a new piglit which tests all format combinations.
What works and what doesn't was deduced by looking at the piglit failures.
