soc/intel/jasperlake: Add FSP UPDs for minimum assertion widths
Add the FSP UPDs for the chipset minimum assertion widths and
Power cycle duration to the chip options which can be configured
per mainboard.
* PchPmSlpS3MinAssert: SLP_S3 Minimum Assertion Width Policy
* PchPmSlpS4MinAssert: SLP_S4 Minimum Assertion Width Policy
* PchPmSlpSusMinAssert: SLP_SUS Minimum Assertion Width Policy
* PchPmSlpAMinAssert: SLP_A Minimum Assertion Width Policy
* PchPmPwrCycDur: PCH PM Reset Power Cycle Duration
* Check to avoid violating the PCH EDS recommendation for the
PchPmPwrCycDur setting.
