drm/bridge: chipone-icn6211: Switch to atomic operations
Replace atomic version of the pre_enable/enable/post_disable
operations to continue the transition to the atomic API.
Also added default drm atomic operations for duplicate, destroy
and reset state API's in order to have smooth transition on
atomic API's.
Tested on Allwinner R16/R40 DSI.
