We can prevent potential incorrect DMA access attempts from the
NIC by enabling bus-master after the reset, and by disabling
bus-master earlier in cleanup.

We no longer support the mgmt device in the ionic driver,
so remove the device id and related code.

Add support for the management port device id. This is to
capture the device and set it up for devlink use, but not set
it up for network operations. We still use a netdev object
in order to use the napi infrasucture for processing adminq
and notifyq messages, we just don't register the netdev.

If the basic ionic interface works but the lif creation fails,
don't fail the probe. This will allow us to use the driver to
help inspect the hw/fw/pci interface for debugging purposes.

Add the netdev ops for managing VFs. Since most of the
management work happens in the NIC firmware, the driver becomes
mostly a pass-through for the network stack commands that want
to control and configure the VFs.
We also tweak ionic_station_set() a little to allow for
the VFs that start off with a zero'd mac address.

Set up the initial NDO structure and callbacks for netdev
to use, and register the netdev. This will allow us to do
a few basic operations on the device, but no traffic yet.

Most of the NIC configuration happens through the AdminQ message
queue. NAPI is used for basic interrupt handling and message
queue management. These routines are set up to be shared among
different types of queues when used in slow-path handling.

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.

The LIF is the Logical Interface, which represents the external
connections. The NIC can multiplex many LIFs to a single port,
but in most setups, LIF0 is the primary control for the port.

The ionic device has a small set of PCI registers, including a

Also adds new DEVLINK_INFO_VERSION_GENERIC tags for
ASIC_ID, ASIC_REV, and FW.
