Intel common: add microcode loading to romstage before fspmemoryinit
The intend is to seek upgraded microcode in RW section and load it before Fsp memoryinit, to ensure any goodness in the microcode update, especially related to memory configuration, can be applied earlier. BUG=chrome-os-partner:50132 BRANCH=glados TEST=Built and boot on kunimintus. Verified microcode gets reloaded. Boot time impact is very minor.
