Subject: [PATCH 04/90] ARM: dts: sun6i: mixtile-loftq: Add USB1 VBUS regulator

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.
