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.
