mb/purism/librem_skl: Disable CLKREQ for NVMe
This effectively reverts: 5086ccef [mb/purism/librem_skl: Fix CLKREQ for 15v3 NVMe]
Some Librem 15v3/v4 boards are showing issues with NVMe detection or booting via SeaBIOS, so revert this until a proper fix can be found.
Test: build / successfully boot Librem 15v4 with problematic NVMe drive.
