If Skylake microcode is being loaded from FIT, Skylake supports the PRMRR/SGX feature. If this is supported the FIT microcode load will set the msr (0x08b) with the patch ID one less than the ID in the microcode binary. This results in microcode getting reloaded again in the bootblock cpu init. Avoid the microcode reload by checking for PRMRR support.
