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 v3: Add some Acked-by, rebased to v4.5.0-rc1

Changes from v2: Improve device tree binding example as noted by Rob
Herring. Rename pcie-thunder-pem.* to pci-thunder-pem.* for better
consistency. Update MAINTAINERS to reflect the changes.

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