mb/purism/librem_skl: Fix CLKREQ for 15v3 NVMe

Per the schematics, SRCCLKREQ2# is used for the NVMe and should be
enabled. Enable CLKREQ for PCIe RP9, and adjust comments to indicate
correct value used per schematic.

Test: build/boot Librem 15v3 with NVMe drive, verify drive identified
properly and no errors in boot log.
