Subject: [PATCH v2 0/6] drm/meson: rework encoders to pass ATTACH_NO_CONNECTOR

This serie finnally reworks the drm/meson driver by extracting the encoders
in their own file and moves to bridge-only callbacks.

This permits passing the ATTACH_NO_CONNECTOR bridge attach flag and finally
use the CVBS & HDMI display-connector driver.

This will ease Martin Blumenstingl writing the HDMI transceiver driver for
the older Meson8/8b SoCs, and sets the proper architecture for the work in
progress MIPI-DSI support.

Finally, this serie will path the way to a removal of the device component
and use the drmm memory management.

Changes since v1 at [1];
 - patch 1: added sam's review tag, fixed include order, fixed doc wording
 - patch 2: added sam's ack tag, switched to dev_dbg()
 - patch 3: moved mode_set to atomic_enable, removed DRM_DEBUG, fixed include order
 - patch 4: added sam's ack tag & applied to drm-misc-next
 - patch 5 & 6: added sam's ack tag
 - patch 7: added sam's review tag, stopped saving connector, moved mode_set to atomic_enable,
 	added missing atomic state callbacks, fixed include order, switched to dev_dbg/dev_err
