linux-firmware: add bbappend to modify firmware file names

Browse Source 
Upstream changes to the brcmfmac driver require a change to the firmware
file names to match the devid and interface type of the Broadcom chipset.
This also makes it easier for one machine to support multiple chipets in
Yocto.
