Subject: [PATCH v3 0/9] NTB: Alter kernel API to support multi-port devices

There are devices, like IDT PCIe-switches, which have more than just two ports.
Particularly one device can have up to eight ports with NTB-function activated.
In order to support such devices, NTB kernel API should be altered since
currently it's optimized to work with two-ports devices only.

Changelog v2:
 - Move comments from cover letter to individual patches
 - Combine patches to make code buildable
 - Alter patchset to support Intel SKX driver
 - Make sure all the API uses the same midx/widx/pidx/sidx arguments notation
 - Move new MW API usage description into Documention
 - Alter Spad/Msg API checking valid function to make spad and msg interfaces optional
 - Alter comments in ntb.h
 - Split: add NTB_SPEED_GEN4 and ntb.h comments into separate patches
 - Put copyrights into some of the existing patches
 - Get rid of TOPO updates

Changelog v3:
 - Get rid of code rearrangements within Intel/AMD drivers
 - Make two-ports NTB API being default
 - Check pidx argument for negative values
 - Translation address methods should return zero in case if not implemented
 - Simplify Scratchpad alterations of ntb_tool client driver
 - ntb.h comments are altered in compliance with port-related API changes
 - Spell check the text
