[PATCH 03/14] drm: bridge: icn6211: Switch to atomic operations

[Marek Vasut <marex@denx.de>]

Use the atomic version of the enable/disable operations to continue
the transition to the atomic API, started with the introduction of
.atomic_get_input_bus_fmts(). This will be needed to access the mode
from the atomic state.
