mb/purism/librem_skl: disable HECI PCI device 

As all librem_skl devices ship with the ME disabled via HAP bit and ME
firmware "neutralized" via me_cleaner, the HECI1 PCI device should be
marked off/disabled to ensure that heci_reset() is not called at the end
of heci_init(), as this causes a 15s timeout delay when booting
(introduced in commit cb2fd20 [soc/intel/common: Add HECI Reset flow in
the CSE driver]).
