mb/system76/rpl: darp9: Add SSD RTD3 configs

Some drives block the CPU from reaching C10 on suspend without the RTD3
config.

Fixes suspend with the following drives:

- Kingston KC3000 (SKC3000D/4096G)
- Kingston HyperX (SHPM2280P2H/240G)
- Solidigm P44 Pro (SSDPFKKW010X7)

The following drives continue to work:

- Samsung 970 Evo (MZVLB250HAHQ)
- WD Black SN770 (WDS250G3X0E)
- WD Green SN350 (WDS240G2G0C-00AJM0)
- WD Blue SN570 (WDS100T3B0C)
