Subject: [PATCH v3 net-next 0/2] ionic: add devlink dev flash support

Add support for using devlink's dev flash facility to update the
firmware on an ionic device.  This is a simple model of pushing the
firmware file to the NIC, asking the NIC to unpack and install the file
into the device, and then selecting it for the next boot.  If any of
these steps fail, the whole transaction is failed.

We don't currently support doing these steps individually.  In the future
we want to be able to list the FW that is installed and selectable but we
don't yet have the API to fully support that.

v3: Changed long dev_cmd timeout on status check calls to a loop around
    calls with a normal timeout, which allows for more intermediate log
    messaging when in a long wait, and for letting other threads run
    dev_cmds if waiting.

v2: Changed "Activate" to "Select" in status messages.
