The generic OF-based 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.
Note that the ARM pcibios functions expect the PCI sysdata to be a pointer
to a struct pci_sys_data. Add a struct pci_sys_data as the first element
in struct gen_pci so that when we use a gen_pci pointer as sysdata, it is
also a pointer to a struct pci_sys_data.
Create and scan the root bus directly without using the ARM
pci_common_init_dev() interface.
[bhelgaas: changelog, move pcie_bus_configure_settings() before
pci_bus_add_devices(), combine !PCI_PROBE_ONLY blocks]
