PCI: host: Add of_pci_get_host_bridge_resources() stub

The pcie-rcar driver can be built for any ARM platform (for COMPILE_TEST)
including those without CONFIG_OF enabled, and that results in a
compile-time error:

drivers/pci/host/pcie-rcar.c: In function 'rcar_pcie_parse_request_of_pci_ranges':
drivers/pci/host/pcie-rcar.c:939:8: error: implicit declaration of function 'of_pci_get_host_bridge_resources' [-Werror=implicit-function-declaration]
err = of_pci_get_host_bridge_resources(np, 0, 0xff, &pci->resources, &iobase);

Add a of_pci_get_host_bridge_resources() stub function defined when
CONFIG_OF_ADDRESS is disabled to allow compile-testing on all platforms.
This mirrors what we do for other OF-specific functions.
