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
