WIP: ARM: tegra: Enable HDMI on Cardhu
Enable the HDMI output and hotplug detection. Note that HDMI doesn't
work on Cardhu for some reason. I remember someone reporting that it
worked at some point in time, but that no longer seems to be true.
A potential issue might be that EMC clocks are too slow, due to them
being set to some safe default, which causes underflow for high HDMI
resolutions.
