arm64: dts: exynos: gs101-oriole: enable USB on this board

Browse Source 
Pixel 6 (Oriole) has a USB-C connector that can act as host or device.

The USB role is detected dynamically using a MAX77759 TCPCI controller,
but since there is no driver for the MAX77759, the role is defaulted to
peripheral, without any endpoints / ports.

This allows Oriole to be configured as a gadget, e.g. using configfs.

As PMIC regulators are not implemented yet, we rely on USB LDOs being
enabled by the bootloader. A placeholder regulator is used for now.
