Drop DPU_PLANE_COLOR_FILL_FLAG and check the DRM solid_fill property to

color_fill field as we can now use drm_plane_state.solid_fill instead,
and pass in drm_plane_state.alpha to _dpu_plane_color_fill_pipe() to
allow userspace to configure the alpha value for the solid fill color.

Please consider accepting drm_plane_state instead and handling alpha
here. Then _dpu_color_fill can accept rgba colour instead of separate
RGB and alpha values.
Hi Dmitry,
Do you mean adding a patch to refactor _dpu_plane_color_fill() to accept
an RGBA8888 color?
Since, currently, the `color` parameter gets truncated to a BGR888 value
and OR'd with the `alpha` parameter [1].
Thanks,
Jessica Zhang
