PCI: xilinx: Remove dependency on ARM-specific struct hw_pci

The Xilinx PCIe host controller driver uses pci_common_init_dev(), which
is ARM-specific and requires the ARM struct hw_pci.  The part of
pci_common_init_dev() that is needed is limited and can be done here
without using hw_pci.

Create and scan the root bus directly without using the ARM
pci_common_init_dev() interface.
