Pass dig_port as an argument to intel_hdcp_init()
and intel_hdcp2_init().
This will be required for HDCP 2.2 stream encryption.

No, actually intel_hdcp_init get called for DP MST in atomic check phase,
in atomic check phase DP MST connector->encoder is not initialize  yet,
it initialize  with DP MST encoder in commit phase.
so using intel_attached_dig_port(connector) results in OOPS in intel_hdcp_init().
