Hi,
This board is configured with CONFIG_USB1_VBUS_PIN="PH24", but no regulator exists in its device tree. Add the regulator, so USB will continue to work when the PHY driver switches to using the regulator uclass instead of a GPIO.
Update the device tree here because it does not exist in Linux.

Looks alright. I cannot test this, but it compiled and matches the defconfig setting.

Queued for sunxi/master.
