nvme: put some AMD PCIE downstream NVME device to simple suspend/resume path

The NVME device pluged in some AMD PCIE root port will resume timeout
from s2idle which caused by NVME power CFG lost in the SMU FW restore.
This issue can be workaround by using PCIe power set with simple
suspend/resume process path instead of APST. In the onwards ASIC will
try do the NVME shutdown save and restore in the BIOS and still need PCIe
power setting to resume from RTD3 for s2idle.
