FR: Add dkms

[tim-gromeyer]

Hello,
can you please add support for dkms? So I don't need to manually build and install this module after every kernel update?

I personally don't use dkms. There is however the arch-pkg, which uses dkms afaik, so you could set it up based on that, and I'm happy to include it via a PR.
