Some Cavium ThunderX processors require quirky access methods for the
config space of the PCIe bridge.

There are two patches:

1) Refactor code in pci-host-generic so that it can more easily be
   used by other drivers.  This splits the driver for CAM and ECAM
   access methods to a separate file from the common host driver code.

2) Add the ThunderX PCIe driver, which leverages the code in

Changes from v1: Split CAM and ECAM code from common driver code as
suggested by Arnd Bergmann.  Fix spelling errors in
