This can be dropped if mp_ops has
.pre_mp_ops:
static void pre_mp_init(void)
{
    const void *patch = intel_microcode_find();
    intel_microcode_load_unlocked(patch);

/* Setup MTRRs based on physical address size. */
    x86_setup_mtrrs_with_detect();
    x86_mtrr_check();
}
.get_microcode_info:
static void get_microcode_info(const void **microcode, int *parallel)
{
    *microcode = intel_microcode_find();
    *parallel = !intel_ht_supported();
