    soc/intel/skylake: Pass proper CPU flex ratio override to FSP
    
    In bootblock, cpu flex ratio is set to non-turbo max.
    
    In FSP UPD, if CpuRatioOverride is zero, then it tries to program cpu
    ratio to zero. Since it is different than the non-zero value programmed
    in bootblock, FSP gives reset.
    
    To avoid the reset, set FSP UPD for CPU flex ratio override to that
    value as set in bootblock.
