drm: rcar-du: Add DRM_MODE_BLEND_PREMULTI support
R-Car DU driver implicitly supports DRM_MODE_BLEND_COVERAGE only.
This adds a support for DRM_MODE_BLEND_PREMULTI. As a consequence,
DRM_MODE_BLEND_PREMULTI becomes the default. If DRM_MODE_BLEND_COVERAGE
is desired, it should be set explicitly.
This behavior comes from how DRM blend mode is supported.
drm_plane_create_blend_mode_property() creates the blend mode property
with the default value of DRM_MODE_BLEND_PREMULTI. This default value
cannot be modified from the atomic driver.
