soc/intel/{icl,jsl,tgl}: Remove SkipMpInit UPD as deprecated
FSP default UPD for SkipMpInit is set to 0 which refers to run CPU
feature programming on all cores (BSP + APs).
Setting SkipMpInit=1 is not recommended as it will only limit CPU
feature programming on BSP.
TEST=Able to perform CPU feature programming by FSP on all cores
using external MP PPI services.
