Merge branch 'bnxt_en-Updates'

Michael Chan says:

====================
bnxt_en: Updates.

This patchset contains these main features:

1. Add the proper logic to support suspend/resume on the new 57500
   chips.
2. Allow Phy configurations from user on a Multihost function if
   supported by fw.
3. devlink NVRAM flashing support.
4. Add a couple of chip IDs, PHY loopback enhancement, and provide
   more RSS contexts to VFs.

v2: Dropped the devlink info patches to address some feedback
    and resubmit for the 5.6 kernel.
====================
