[PATCH] arm64: dts: exynos: gs101-pixel-common: add supply and regulator properties

[Amit Sunil Dhamne via B4 Relay]

From: Amit Sunil Dhamne <amitsd at google.com>

Add power supply and regulator properties to the MAX77759 pmic. The
usb-typec device will reference the regulator provided by the pmic as
it supplies vbus to the typec device when operating in power source mode.
