A regular M.2 NVMe SSD shows up on RP9 and runs at x4 width.
Optane memory module shows up as 2 NVMe devices in x2 config:
- NVMe storage device uses RP9
- NVMe Optane memory uses RP11
Note: These two devices are sharing CLK PINs because of same M.2 slot.
TEST=Build and boot ADL RVP board using Intel Optane card.
