mb/purism/librem_skl: Disable CLKREQ for NVMe
This effectively reverts commit 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.
