The firmware download you point to has a license which does not allow for redistribution of the firmware, therefore we cannot add it to Ubuntu's linux-firmware package. I checked upstream linux-firmware but the firmware isn't present there.
I'm marking this confirmed, but unfortunately we can't do anything unless Broadcom provides a license which allows us to redistribute the firmware.
