[24.2] freedreno: Fix iova faults on a7xx
I tracked down the issue #11845 (closed) in 24.2.x (but not main or 24.3.x) to missing 270e5958, the important bit being setting RB_BLIT_CLEAR_MODE
, which slipped in as part of the larger refactor. Ironically that register was renamed in b88b0768, which is probably not reasonable to cherry-pick.
Alternatively I could make a one-liner fix that is specific to 24.2 branch, if that is preferred.
