drm: Introduce solid fill DRM plane property
Document and add support for solid_fill property to drm_plane. In
addition, add support for setting and getting the values for solid_fill.
To enable solid fill planes, userspace must assign a property blob to
the "solid_fill" plane property containing the following information:
struct drm_mode_solid_fill {
u32 r, g, b, pad;
};
