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.
