From: Xi Ruoyao

ZHITAI TiPro5000 SSDs has the same APST sleep problem as its cousin,
TiPro7000. The quirk for TiPro7000 has been added in
commit 6b961bce50e4 ("nvme-pci: avoid the deepest sleep state on
ZHITAI TiPro7000 SSDs"), use the same quirk for TiPro5000.

The ASPT data from "nvme id-ctrl /dev/nvme1":
