[net-next v3 1/3] bnge: Pass BAR1 doorbell mapping to RoCE auxiliary device

[Siva Reddy Kallam <siva.kallam@broadcom.com>]

From: Saswati Das <saswati.das@broadcom.com>

Pass the L2 driver's BAR1 doorbell mapping to struct bnge_auxr_dev
alongside the existing BAR0 mapping.

This exposes the doorbell aperture base to the RoCE auxiliary device
so that the RDMA driver can access doorbell registers when configuring
firmware communication channels.
