Currently the dispatching of link status events is implemented by each RDMA driver independently, and most of them have very similar patterns. Add support for this in ib_core so that we can get rid of duplicate codes in each driver. A new last_port_state is added in ib_port_cache to cache the port state of the last link status events dispatching. The original port_state in ib_port_cache is not used here because it will be updated when ib_dispatch_event() is called, which means it may be changed between two link status events, and may lead to a loss of event dispatching. Some drivers currently have some private stuff in their link status events handler in addition to event dispatching, and cannot be perfectly integrated into the ib_core handling process. For these drivers, add a new ops report_port_event() so that they can keep their current processing. Finally, events of LAG devices are not supported yet in this patch as currently there is no way to obtain ibdev from upper netdev in ib_core. This can be a TODO work after the core have more support for LAG.
