soc/intel/elkhartlake: Update HECI Control Status Register settings
For EHL, SpiProtectionMode is added to HFSTS register #1.
The original Manufacturing Mode is detected via FpfSocConfigLock
instead. If FpfSocConfigLock=1, means it is in Menufacturing Mode,
and it is in EOM (End Of Manufacturing) when FpfSocConfigLock=0.
