    soc/intel/apollolake: Try to update BSP microcode from cbfs
    
    The microcode for the BSP gets loaded early from the fit table, but in
    case we have newer microcode in cbfs, try to load it again from cbfs.
    
    BUG=53013
    TEST=Boot and verify that microcode tries to load into the BSP.
