firmware files missing on mainline kernel

[EvilOlaf]

Not sure if it is worth mentioning but when running mainline kernel quite a bunch of firmware files are missing. Did not much testing if this has an impact resulting in either disfunctionality of features or lower performance in graphics for example.

Anyway this can be partially be fixed by installing the latest linux-firmware package available, to say for impish at the moment: https://packages.ubuntu.com/de/impish/linux-firmware
It reduces the amount of "missing firmware" warnings and comes with more recent Renoir firmware files.

As for me I am running Linux Mint 20 based on Ubuntu Focal with kernel 5.13.13 with the mentioned above firmware package without issues.

This is obviously not a bug report but I cannot remove the label :P
