[PATCH v1 1/7] drm/bridge: ps8640: Use atomic variants of drm_bridge_funcs

[Sam Ravnborg <sam@ravnborg.org>]

The atomic variants of enable/disable in drm_bridge_funcs are the
preferred operations - introduce these.

The ps8640 driver used the non-atomic variants of the drm_bridge chain
functions - convert these to the atomic variants.
