mb/google/volteer: Deduplicate lockdown config

The setting `chipset_lockdown` has the same configuration for all
variants and they also match with the baseboard configuration. Thus,
remove it from the variant overridetrees.

Built google/delbin with `BUILD_TIMELESS=1` and coreboot.rom
remains the same.
