[linux-yocto] [kernel v5.10/standard/nxp-sdk-5.4/nxp-imx8][PATCH] PCI: imx: Update the method of obtaining PCI bridge resources to correctly identify the pci device

[Xiaolei Wang]

The PCI bridge resources are stored in pci_host_bridge.windows,
mem_base under pcie_port has been removed, so update the resources
interface to correctly identify pcie device
