Subject: [PATCH] ARM: tegra: Correct which USB controller has the UTMI pad registers

It should be the first controller, not the second.

This broke USB after 6261b06 ("regulator: Defer lookup of supply to
regulator_get"), because it changed the order in which the controllers
were probed.

The fix for this issue was suggested by Mikko Perttunen.
