The GPD Win 5 is a new device by GPD with an AMD AI MAX 385/395 chip.
It uses the same fan control registers as the GPD Win Duo. This
information was provided by GPD.

The GPD Win 5 has dual fans, as noted in [1], there is potential that
they might be able to be controlled independently (duo writes on two
registers).

However, for my application I do not need independent controls so for
me this is good to merge.

If a follow-up patch separates the fans, I will not treat it as a
breaking ABI change and will just update my userspace, so it will be
fine to merge by me. Just, please cc when posting.

I verified the functionality of this patch.
