drm/amd/display: Fix direct scanout alpha on some DRM_FORMATs

[Why]

DM was declaring it's own list of has_alpha DRM formats to check against
for enabling alpha blending, when the format->has_alpha already does
that for us.

The self-declared list missed some has_alpha formats, causing
direct-scanout planes with such formats to appear opaque.

[How]

Drop the self-declared list, instead use the format->has_alpha field
directly.
