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
