Borislav Petkov 4167709bbf x86/microcode/intel: Add a helper which gives the microcode revision ...

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.
