freedreno/a4xx: fix *_NONE enum conversion
Commit e369b893 ("freedreno: Use explicit *_NONE enum for undefined formats") only partially converts ~0 to *_NONE enum. It breaks texture support, and glmark2 texture scene gives a black screen.
Adding the missing conversion of ~0 to *_NONE enum fixes the issue.
