linux-firmware: update, merge in OE classic updates, fix packaging
Update: move to latest SRCREV, use non-kernel.org URI
Merge: wl12xx symlink + packaging, install all firmwares
Fix: * all entries in PACKAGES are in PROVIDES already
* A package always RPROVIDES itself
* A file can only get packaged *once* so only one rtlwifi package will get the license
