drm/bridge: dw-mipi-dsi: Switch to atomic operations 



Replace atomic version of the enable/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 Engicam i.Core STM32MP1 SoM.
