drm: writeback: Add client capability for exposing writeback connectors
Due to the fact that writeback connectors behave in a special way
in DRM (they always report being disconnected) we might confuse some
userspace. Add a client capability for writeback connectors that will
filter them out for clients that don't understand the capability.
Changelog:
- only accept the capability if the client has already set the
DRM_CLIENT_CAP_ATOMIC one.
