net: bnge: add AUXILIARY_BUS to Kconfig dependencies

The build can currently fail with

    ld: drivers/net/ethernet/broadcom/bnge/bnge_auxr.o: in function `bnge_rdma_aux_device_add':
    bnge_auxr.c:(.text+0x366): undefined reference to `__auxiliary_device_add'
    ld: drivers/net/ethernet/broadcom/bnge/bnge_auxr.o: in function `bnge_rdma_aux_device_init':
    bnge_auxr.c:(.text+0x43c): undefined reference to `auxiliary_device_init'

if BNGE is enabled but no other driver pulls in AUXILIARY_BUS.

Select AUXILIARY_BUS in BNGE like in all other drivers which create
an auxiliary_device.
