commit 4167709bbf826512a52ebd6aafda2be104adaec9 upstream. Since on Intel we're required to do CPUID(1) first, before reading the microcode revision MSR, let's add a special helper which does the required steps so that we don't forget to do them next time, when we want to read the microcode revision.
