We are seeing a issue when we close the lid of a laptop or dock a
monitor hdcp content is not being reenabled automatically this is
because 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 first and second patch refactors the code while the third one adds the
new conditions to enable hdcp.
