[linux-yocto] [linux-yocto-dev standard/xlnx-soc][PATCH 1/2] PCI: XDMA PL: use pci_parse_request_of_pci_ranges instead of devm_of_pci_get_host_bridge_resources

[quanyang.wang]

From: Quanyang Wang <quanyang.w...@windriver.com>

Because of mainline commit 3b55809cf91f ("PCI: Make
devm_of_pci_get_host_bridge_resources() static"), use
pci_parse_request_of_pci_ranges instead of
devm_of_pci_get_host_bridge_resources().
