arm64: dts: mediatek: mt8395-genio-common: add MT6360 PMIC supplies

The Mediatek Genio 1200-EVK board has a MT6360 PMIC, powered by the
board system power rail (VSYS) and an additional system power rail
(VSYS_BUCK).
In the board devicetree, the power supply inputs for its buck and ldo
regulators are either incorrect (LDO_VIN3) or missing (LDO_VIN1/2,
BUCK_VIN1/2).

So, add VSYS_BUCK regulator node and the proper supply inputs for this
PMIC.
