[PATCH v4 0/7] PCI: dwc: Miscellaneous fixes and cleanups

[Kishon Vijay Abraham I]

This should be the final set of cleanups/fixes before endpoint
support can be merged.

Keerthy's patch is a general fix in dra7xx driver and is not
directly related to endpoint mode.

This v1 of this series was previously sent with a different
cover letter $subject [1]

Changes from v3:
*) instead of changing all the callers of dbi accessors (taking
   dbi_base and size), manage it using static inline as suggested
   by Niklas (used static inline instead of macros because of
   checkpatch error).

Changes from v2:
*) Kconfig changes that was spilled into a patch is removed.
*) In addition to renaming _unroll() to _ob_unroll(), all the
   _unroll configurations is also moved a separate function.

Changes from v1:
*) included a patch to rename _unroll() to _ob_unroll() as
   similar thing has to be done for inbound window in the case
   of EP mode.
*) used 'size_t' instead of 'int' for specifying the size
   in read_dbi/write_dbi function arguments.
*) Populate cpu_addr_fixup ops for artpec6 as suggested by
   Niklas

This series is based on 4.11-rc1
