drm/i915: Fix per-pixel alpha with CCS
commit 77ce94dbe586c1a6a26cf021c08109c9ce71b3e0 upstream.
We forgot to set .has_alpha=true for the A+CCS formats when the code
started to consult .has_alpha. This manifests as A+CCS being treated
as X+CCS which means no per-pixel alpha blending. Fix the format
list appropriately.
