linux-firmware: separate packages for Broadcom FullMAC PCIe firmwares

Using few packages will allow saving some space by decreasing rootfs
size. Dropping 43602a1 firmware saves 316 580 B. Dropping 4366b1 saves
468 188 B.

Moreover there are more firmware files that may require packaging and
even more to come later (e.g. 4366c0).

This can especially useful now, with per device rootfs.
