Add preliminary support for Nuvoton NCT6799D

[Alexx999]

Partially addresses #843
On X670E Hero it allows controlling fans (my primary goal) but the temps seem wrong so this is definitely not 100% complete just yet.

Search arround Github a bit, found this file:
https://github.com/NetBSD/src/blob/8320b6cc18fa066411b30896566869b05eb29ed7/sys/dev/ic/nslm7x.c

seems to contains most register addresses you need.

Good to see progress about this, I am about to move from current AMD AM4 platform to new AM5 with Hero X670E board, (just waiting PSU to arrive), and FanControl is a must,, I have been using it since I found it, also donated to the project :)

[Rem0o]

@jstar81 consider donating to people contributing to this repo too, like @PhyxionNL and @Alexx999, the backend work is not to be neglected.

[jstar81]

@Rem0o thanks for your reply, I donated $10 to @PhyxionNL :) Alex is missing Sponsor option for some reason

[Alexx999]

@jstar81 Living in Ukraine has some downsides sometimes, lack of GitHub sponsorship support is one of them. Although, it's not the most pressing problem at the time being 🙂

@Rem0o Yeah, I saw the NetBSD code, it has some neat bits (i.e. 13 bit ID checks) but the sensors list used is way back from NCT6779D which is not any better than what we have here.

Thank you! Built libs for FanControl and now it works with my X670 mobo

Are you able to help noobies like me, how to build libs?
I would really like to start using FanControl & LibreHardwareMonitor with my new X670E setup :( But so far doesn't recognize any fans except my GPU. Asus own software isn't good.

@Alexx999 Do you want to do anything still with this PR?

[Alexx999]

@PhyxionNL I tried looking into weird temp readings, but without any info/datasheets it's non-trivial, to say the least. Also, CPUID hwmon has exactly the same readings :)
So I'd say it should be merged as-is as there's no readily available info to fix it anyway.

Yeah, too bad these datasheets are always missing, so this sounds good, thanks!

Uh, Question. I've stumbled on this while looking for linux-upstream support of my ASRock X670E PG Lighting (I know different vendor). In my case, the SuperIO identifies itself with the same 0xd802 ID, but mine has the label "NCT6796D-S" on it.
