Hunt and gather more missing linux-firmware

[rxrbln]

The linux kernel drivers require many more firmware files than are distributed in linux-firmware, which can be checked via something like: for f in $(modinfo -F firmware find /lib/modules -name *ko); do ls /lib/firmware/$f >/dev/null ; done

at the time of writing some 361.

It would be good to package the most important ones in package/firmware/ packages.
