soc/intel/tigerlake: Add CpuReplacementCheck to chip options
Add CpuReplacementCheck to chip options to control UPD FSPM SkipCpuReplacementCheck from devicetree. This UPD allows platforms with soldered down SoC to skip CPU replacement check to avoid a forced MRC traning. TEST=boot and verified with volteer Change-Id: Ic5782723ac3a204f2af657fac9944fb41fc03f4d Signed-off-by: Jamie Ryu <jamie.m.ryu@intel.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/42788 Reviewed-by: Nick Vaccaro <nvaccaro@google.com> Tested-by: build bot (Jenkins) <no-reply@coreboot.org>
