Commit da7716a249b699978fb5 ("drm/msm/dpu: Add support for XR30 format") enabled
support for the 10-bit XR30 color format but missed enabling support for the
corresponding per-pixel alpha-blending AR30 color format.
Declaring only XR30 but not AR30 color format support can trigger bugs in
userspace. KDE KWin compositor versions prior to 5.27.3 for example prefer
10-bit color formats, rendering a 1cm^2 black box around the cursor due to
missing per-pixel alpha-blending.
