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.
