Merge branch 'octeontx2-af-NPA-and-NIX-blocks-initialization'

Sunil Goutham says:

====================
octeontx2-af: NPA and NIX blocks initialization

This patchset is a continuation to earlier submitted patch series
to add a new driver for Marvell's OcteonTX2 SOC's
Resource virtualization unit (RVU) admin function driver.

octeontx2-af: Add RVU Admin Function driver
https://www.spinics.net/lists/netdev/msg528272.html

This patch series adds logic for the following.
- Modified register polling loop to use time_before(jiffies, timeout),
  as suggested by Arnd Bergmann.
- Support to forward interface link status notifications sent by
  firmware to registered PFs mapped to a CGX::LMAC.
- Support to set CGX LMAC in loopback mode, retrieve stats,
  configure DMAC filters at CGX level etc.
- Network pool allocator (NPA) functional block initialization,
  admin queue support, NPALF aura/pool contexts memory allocation, init
  and deinit.
- Network interface controller (NIX) functional block basic init,
  admin queue support, NIXLF RQ/CQ/SQ HW contexts memory allocation,
  init and deinit.
