This patch series include an attempt to avoid the use of custom
read and writes in driver code and use PCI subsystem common ones.

In order to do this 'map_bus' callback is implemented and also
data structures for driver are included. The regs base address
is being readed from device tree and the driver gets clean a lot
of code.

Changes in v3:
    - Include new patches to delete all RALINK_BASE definition 
      dependant code and be able to avoid use of pci_legacy code.
    - use devm_of_pci_get_host_bridge_resources, 
      devm_request_pci_bus_resources and pci_scan_root_bus_bridge
      and pci_bus_add_devices 

Changes in v2:
    - squash PATCH 1 and PATCH 2 of previous series in only PATCH 1
    - Change name for host structure.
    - Create a new port structure (platform has 3 pcie controllers)
    - Replace the use of pci_generic_config_[read|write]32 in favour
      of pci_generic_config_[read|write] and change map_bus implemen-
      tation for hopefully the right one.
