The FSP may fail to detect PCIe 4.0 devices in PCIe 3.0 slots on S3
resume. This issue has only been experienced on lemp12, and only with
Samsung drives, but implies it could happen on other systems or with
other drives as well. A timeout of 50ms is arbitrarily chosen.
Tested on lemp12 with Samsung 980 PRO (FW: 3B2QGXA7, 5B2QGXA7) and 990
PRO (FW: 4B2QJXD7) drives.
