[PATCH v1 07/12] drm/bridge: tc358767: Use drm_bridge_funcs.atomic_check

[Sam Ravnborg <sam@ravnborg.org>]

When atomic_check() is defined, then mode_fixup() is ignored,
so it had no effect that drm_bridge_funcs.mode_fixup was assigned.
Embed the original implementation in the caller and drop the function.
