After we do a fw upgrade and refill the ionic->ident.dev, we
also need to update the other identity info. Since the lif
identity needs to be updated each time the ionic identity is
refreshed, we can pull it into ionic_identify().
The debugfs entry is moved so that it doesn't cause an
error message when the data is refreshed after the fw upgrade.

in_interrupt() is ill defined and does not provide what the name
suggests. The usage especially in driver code is deprecated and a tree wide
effort to clean up and consolidate the (ab)usage of in_interrupt() and
related checks is happening.
In this case the check covers only parts of the contexts in which these
functions cannot be called. It fails to detect preemption or interrupt
disabled invocations.
As the functions which are invoked from ionic_adminq_post() and
ionic_dev_cmd_wait() contain a broad variety of checks (always enabled or
debug option dependent) which cover all invalid conditions already, there
is no point in having inconsistent warnings in those drivers.
Just remove them.

Add support for firmware update through the devlink interface.
This update copies the firmware object into the device, asks
the current firmware to install it, then asks the firmware to
select the new firmware for the next boot-up.
The install and select steps are launched as asynchronous
requests, which are then followed up with status request
commands. These status request commands will be answered with
an EAGAIN return value and will try again until the request
has completed or reached the timeout specified.

The version 1 Tx queues can use longer SG lists than the
original version 0 queues, but we need to check to see if the
firmware supports the v1 Tx queues. This implements the queue
type query for all queue types, and uses the information to
set up for using the longer Tx SG lists.
Because the Tx SG list can be longer, we need to limit the
max ring length to be sure we stay inside the boundaries of a
DMA allocation max size, so we lower the max Tx ring size.
The driver sets its highest known version in the Q_IDENTITY
command, and the FW returns the highest version that it knows,
bounded by the driver's version. The negotiated version number
is later used in the Q_INIT commands.

When the FW RESET event comes to the driver from the firmware,
or the fw_status goes to 0 (stopped) or to 0xff (no PCI
connection), then shut down the driver activity. This event
signals a FW upgrade where we need to quiesce all operations and
wait for the FW to restart. The FW will continue the update
process once it sees all the LIFs are reset. When the update
process is done it will set the fw_status back to RUNNING.
Meanwhile, the heartbeat check continues and when the fw_status
is seen as set to running we can restart the driver operations.

check but is still alive and will process the pending request, so don't

all down at once, but still wants to see that last LIF disable request.
