[PATCH v5 1/2] arm64: dts: imx94: Add Root Port node

[hongxing . zhu]

From: Richard Zhu <hongxing.zhu@xxxxxxx>

Since describing the PCIe PERST# property under Host Bridge node is now
deprecated, it is recommended to add it to the Root Port node, so
creating the Root Port node and pave the path to add the reset-gpios
and so on properties in Root Port later.
