There are two ways to do it. First you can just embed the firmware
in the driver itself. Second you can have the driver use the API
in kern/kern_firmware.c to load the firmware. Doing it the second
way only works once root has been mounted so automating it in the
driver would require creating a SYSINIT that runs after root has
mounted or loading the driver with kldload after the system has booted.
