[PATCH 01/15] bnge: Add infrastructure support for RoCE MPC channels

[Siva Reddy Kallam]

From: Saswati Das <saswati.das@xxxxxxxxxxxx>

Add the initial L2 driver plumbing for RoCE MPC (PRIMATE channel)
support:

- Plumb BAR1 through to the RoCE auxiliary device info, alongside the
  existing BAR0, so the RoCE driver can reach the doorbell BAR.

This will be used by follow-on patches to issue RoCE commands over the
MPC channels to the firmware.
