Imo this shouldn't check for intel gen at all. But instead enumerate HDMI
ports and check for the content protection property. If not there -> skip,
if there -> run the test and pass/fail.
That way the test should properly skip on any platform/kernel combo that
doesn't have hdcp - igt is supposed to be somewhat backwards/forward
compatible (within reasons, which amounts to about 1 year or so).
