dalboz: move HDMI HPD off the IO expander
On earlier board versions (prior to version 2) the hotplug detect signal
was routed only through an IO expander, but latency in that
configuration is too high- new hardware routes it directly to an EC
GPIO. Because the old one was too slow, drop support for it and use the
new direct IO exclusively.
BUG=b:153399461
TEST=HPD passthrough works on new boards.
