[PATCH V5 3/7] arm64: dts: imx8mm-evk: Add power supply property to Root Port node

[Sherry Sun (OSS)]

From: Sherry Sun <sherry.sun@xxxxxxx>

Add the power supply property to the Root Port child node to support the
new PCI pwrctrl framework.

Legacy power supply property is retained for backward compatibility with
existing kernels. New device trees should specify power supply at the
Root Port level to utilize the pwrctrl framework.
