RDMA/erdma: Probe the erdma RoCEv2 device

Browse source 
Currently, the erdma driver supports both the iWARP and RoCEv2 protocols.
The erdma driver reads the ERDMA_REGS_DEV_PROTO_REG register to identify
the protocol used by the erdma device. Since each protocol requires
different ib_device_ops, we introduce the erdma_device_ops_iwarp and
erdma_device_ops_rocev2 for iWARP and RoCEv2 protocols, respectively.
