Add support for stopping and disabling them, and reset them as part of the hard-reset procedure of GAUDI. This will allow the user to submit work to the NICs. Add support for receiving events on QMAN errors from the firmware. However, the nic_ports_mask is still initialized to 0. That means this code won't initialize the QMANs just yet. That will be in a later patch.
