Subject: [PATCH 2/6] drm/atomic: add interlaced and ycbcr_420 flags to
 connector's state dump

Although the interlace_allowed and ycbcr_420_allowed flags are a part of
the struct drm_connector rather than struct drm_connector_state, still
include them into state dump in order to ease debugging of the setup
issues.
