I915 needs to send the index of the transcoder as per ME FW.
To support this, define enum mei_fw_ddi and add as a member into
the struct hdcp_port_data.

Also, this is a bit odd, coz ports above can't do HDCP, so it doesn't
make sense to have them here. But seems like we want to be in sync with
MEI FW definitions, so we should change the function
intel_get_mei_fw_ddi_index to accept only from ports A to D, not above
or below.
