[PATCH v4 04/11] drm/bridge: tc358767: Convert to atomic ops

[Marek Vasut]

Use the atomic version of the enable/disable operations to continue the
transition to the atomic API. This will be needed to access the mode
from the atomic state.

Tested-by: Lucas Stach <l.stach at pengutronix.de> # In both DPI to eDP and DSI to DPI mode.
