Bug Description
=== SRU Justification ===
[Impact]
ID is missing so the devcie isn't bound to AHCI driver.
Without the driver, we can't check the existence of remapped NVMe.
[Fix]
Add one missing ID.
[Test]
Use lspci to see if the device is bound to ahci driver. Test positive
after applying the patch.
[Regression Potential]
Low. This is a trivial fix which limits to one specific device.
=== Original Bug Report ===

The patch is needed to improve the installer user experience on Focal for Intel RST/RAID mode users, who switch from Windows to Linux.
