When we dock a monitor we end up with a enable and disable connector
cycle but if hdcp content is running we get the userspace in
enabled state and driver maintaining a undesired state which causes
the content to stop playing and we only enabe hdcp if the userspace
state in desired. This patch fixes that.

--v2
-Move code to intel_hdcp [Jani]
