drm/i915/hdcp: Use intel_connector as argument for hdcp_2_2_capable

Use intel_connector as argument instead of intel_digital_port in
hdcp_2_2_capable function and dig_port can be later derived from
connector. This will help with getting the correct hdcp version of
particular monitor in a MST setup.
