Browse Source 
Tested with the following drives:

- Crucial P5 Plus (CT500P5PSSD8)
- Kingston KC3000 (SKC3000S/512G)
- Sabrent Rocket NVMe 4.0 (SB-ROCKET-NVMEe4-500)
- Samsung 970 EVO (MZ-V7E250)
- Samsung 970 EVO Plus (MZ-V7S250)
- Samsung 980 PRO (MZ-V8P2T0)
- WD Black SN850X (WDS100T2XD0E)
- WD Blue SN580 (WDS500G2B0C)
- WD Green SN350 (WDS240G2G0C)

Test:

- PCH asserts `SLP_S0#` during suspend (power LED blinks)
- `slp_s0_residency_usec` increases after suspend
