drm function to update the content protection property state and to
generate a uevent is invoked from the intel hdcp property work.

Hence whenever kernel changes the property state, userspace will be
updated with a uevent.

Need a ACK for uevent generating uAPI from userspace.

v2:
  state update is moved into drm function [daniel]
