arm64: dts: imx8mq-evk: Add power supply properties to Root Port node
Add the power supply properties to the Root Port child nodes to support
the new PCI pwrctrl framework.
Legacy power supply properties are retained for backward compatibility
with existing kernels. New device trees should specify power supplies at
the Root Port level to utilize the pwrctrl framework.
