Only one functional change, reversed the hdcp_1x/2x_present bits in the
QUERY_STREAM_ENCRYPTION_STATUS parsing with a comment explaining my
confusion.

Other than that, lots of rebasing, the most notable being the
s/intel_dig_port/dig_port/ rename. 

Every patch now has a Reviewed-by tag now, I've done build tests on each
patch and tested the set as a whole. Hopefully we can get this landed.
