Add limit tables and DMI entries for AMD APU-based handheld devices:
- 15W class: AYANEO AIR
- 18W class: AYANEO AIR Plus/Pro
- 25W class: AYANEO AIR 1S, NEXT/KUN
- 28W class: GPD Win Mini/4/Max 2, GPD Duo, GPD Pocket 4, AYANEO 2,
OrangePi NEO-01, SuiPlay0X1
- 30W class: AYANEO FLIP/GEEK/SLIDE/3, AOKZOE A1/A1X/A2,
OneXPlayer F1Pro/2/X1/G1, AYN Loki Max, Zeenix Pro
Also add SoC strings for Ryzen AI, Ryzen 8000/7040/6000/5000
families, extending support beyond the initial AI MAX series.
There are a lot of numbers here. Where did they all come from? What are guesses? What came from RE? What came from documentation?
How do you know these are good for the thermal design of the platform?
I appreciate some of them could be cargo culted from another codebase, but I think it would be a good idea to document which ones are more likely to be accurate and why.
