[PATCH v2] drm/bridge: adv7511: Switch to atomic operations

[Jesse Van Gavere]

Use the atomic version of enable/disable.

To support bridges where bus format negotiation is needed such as TIDSS we
need to implement atomic_get_input_bus_fmts, prepare the driver for this by
switching the existing operations to it's atomic variants.

Changes in v2:
- Reword commit message to make clear this commit is to prepare for adding
  input bus formats to make the driver work with systems like TIDSS which
  expect this capability as suggested by Dmitry
