USB_VBUS_EN0 regulator (regulator@11) is being overwritten by vdd-cam-1v2
regulator. This commit rearrange USB_VBUS_EN0 to be regulator@14.

Thanks for catching this! We should add the 'Fixes:' tag.

By the way, I assume that VBUS is currently broken for the OTG port.
Without this change is that USB port completely broken? I am wondering
if we need to CC stable@vger.kernel.org on this.

Thanks for review. I will submit v2 and add 'Fixes:' tag.

You are correct. Host mode at the OTG port is currently broken because VBUS is
not supplied to the OTG port. I will CC stable@vger.kernel.org when send v2.
