[0/2] Add Auxiliary driver support

Message

Add auxiliary device driver for Broadcom devices.
The bnxt_en driver will register and initialize an aux device
if RDMA is enabled in the underlying device.
The bnxt_re driver will then probe and initialize the
RoCE interfaces with the infiniband stack.

Please apply.

Add auxiliary device driver for Broadcom devices.
The bnxt_en driver will register and initialize an aux device
if RDMA is enabled in the underlying device.
The bnxt_re driver will then probe and initialize the
RoCE interfaces with the infiniband stack.

v1->v2:
- Incorporated review comments including usage of ulp_id &
  complex function indirections.
- Used function calls provided by auxiliary bus interface 
  instead of proprietary calls.
- Refactor code to remove ROCE driver's access to bnxt structure.

Please apply. Thanks.
