What do we want to optimise for? Seriously, wpi is using the same
approach to wifi as ~every other device does. Keep the firmware in
memory for whenever you will need it.

Note that this is not only resume time, but it will load the firmware
whenever if_init is called. If you really worry about the memory usage,
the static bus dma allocation should be eliminated first. That is larger
than the size of the firmware. But I don't think worrying about the
150KB image is  justified.
