arm64: dts: imx943-evk: add PCIe root port node and according properties

Browse Source 
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 add the reset-gpios property in root port.

Move the regulator to root port nodes as well, because that the PCI pwrctrl
framework had been integrated into pci-imx6 driver.

The backward compatibility is not a concern since i.MX94 is a newly
introduced platform that is still under active development.
