Can not see the storage with Intel RAID On mode enabled on Intel Comet
Lake

New

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 ===

enabled in the BIOS.
The Dell Latitude 5310 is an Intel Comet Lake platform, which missing
the ID[1] in the kernel.
