arm64: dts: exynos: gs101-oriole: add placeholder regulators for USB phy

The USB phy requires various power supplies to work.

While we don't have a PMIC driver yet, the supplies should still be
added to the DT.

Add some placeholders, which will be replaced with the real ones once
we implement PMIC.
