Subject: [PATCH v2 2/9] drm/msm: add arrays listing formats supported by
MDP4/MDP5 hardware
MDP4 and MDP5 drivers enumerate supported formats each time the plane is
created. In preparation to merger of MDP DPU format databases, define
precise formats list, so that changes to the database do not cause the
driver to add unsupported format to the list.
