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]
