linux-firmware: add separate packages for all brcm files
* no changes in the content of previously existing packages
* include some silly commands I've used to "parse" WHENCE file to
generate these, some manual changes are still needed, like separating
cypress licensed files, removing duplicates when 2 files are included
in the same package (bcm4356-pcie is exception because sdio and pcie
files have different license).
