[6/7] ARM: tegra: dalmore - Add +5V HDMI supply

This supply controls the +5V pin on the HDMI connector, which in turn is
used by attached sinks to return the hotplug detect signal.

Note: Unfortunately I do have an A05 Dalmore, and from what I can tell
HDMI is actually one of the areas where there have been changes between
A04 and A05. It'd be great if somebody could check that this actually
works. Also note that it requires Tegra DRM patches that are currently
in linux-next to enable the +5V regulator.
