ARM: tegra: fix VBUS regulator GPIO polarity in DT 

Commit 4c94c8b "ARM: tegra: update device trees for USB binding rework"
added regulator definitions for GPIO-controlled USB VBUS. However, none
of these contained the essential DT property enable-active-high. Add
this so that the regulator definitions are correct.
