[RFC v4 4/4] platform/x86/amd: dptc: Add device entries for handheld PCs

[Antheas Kapenekakis]

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.
