drm: bridge: adv7511: Enable DRM_BRIDGE_OP_HPD based on HPD interrupt 

Connector detection using poll method won't work in case of bridge
attached to the encoder with the flag DRM_BRIDGE_ATTACH_NO_CONNECTOR, as
the code defaults to HPD.

Enable DRM_BRIDGE_OP_HPD based on HPD interrupt availability, so that
it will fall back to polling, if HPD is not available.
