[PATCH v2] arm64: dts: exynos: gs101-pixel-common: add supply and regulator properties

[Amit Sunil Dhamne via B4 Relay]

From: Amit Sunil Dhamne <amitsd@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.

Changes in v2:
- Added a line between property and child node as per DTS coding std.
  (Krzysztof Kozlowski)
- Added the "power-supplies" property immediately after the prev
  property without leaving a line space.
- Link to v1: https://lore.kernel.org/r/20260224-max77759-charger-dts-v1-1-b443545c04aa@google.com
