[PATCH v1 10/12] drm/omapdrm: Use drm_bridge_funcs.atomic_check

[Sam Ravnborg <sam@ravnborg.org>]

Replace the deprecated drm_bridge_funcs.mode_fixup() with
drm_bridge_funcs.atomic_check().

drm_bridge_funcs.atomic_check() requires the atomic state operations,
update these to the default implementations.
Likewise update enable/disable to their atomic variants.

With these changes omapdrm now implement the full bridge atomic API.
