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.

I'm sending this to arm-soc to be taken into v3.11-rc1. However, if it
won't get in until -rc2, let me know; I'd be tempted not to fix it in
3.11 in that case, so I don't have to wait until v3.11-rc2 before
applying patches that use these new regulators, since they rely on this
fix going in first.

Applied to fixes branch, thanks!
