Some hardware only supports the COVERAGE blend mode and lacks PREMULTI support entirely. DRM currently requires that PREMULTI is present when creating a blend mode property, which prevents such drivers from being properly upstreamed.
This series remove such restriction and allow drivers to create a blend mode property without PREMULTI.
v2: force drivers to expose blend mode if plane supports alpha property or pixel format with alpha.
