ionic: Add interrupts and doorbells
The ionic interrupt model is based on interrupt control blocks
accessed through the PCI BAR. Doorbell registers are used by
the driver to signal to the NIC that requests are waiting on
the message queues. Interrupts are used by the NIC to signal
to the driver that answers are waiting on the completion queues.
