The ubtbcmfw(4) driver fails to compile, as noted by PR kern/34219.
While it can be made to compile, the paradigm is not quite right because it attempts to contact the filesystem during autoconfig which sometimes causes a panic. Even if that was fixed, there is another potential problem in that the driver tries/sleeps/tries/sleeps and the sleep could theoretically sleep past the rc.d/btconfig stage and the controller would remain unconfigured. So, I have prepared a different method for loading the firmware to Broadcom BCM2033 chip based devices. A package 'sysutils/bcmfw' will load the firmware files via a ugen(4) device interface. This update removes the ubtbcmfw(4) driver and adds a table to the ubt(4) driver so that it will not attach to Broadcom BCM2033 based devices before the firmware was loaded. This fixes kern/34219
