[PATCH 1/3] arm64: dts: mediatek: mt8390-genio-common: add MT6319 PMIC support

[Louis-Alexis Eyraud]

Mediatek Genio 510 and 700-EVK boards integrate a MT6319 PMIC, powered
by the board system power rail (VSYS) and connected to the SPMI
interface. It provides buck regulators for CPU core power supplies in
particular.

Add the needed nodes in the board common dtsi to enable its support.
