soc/intel/{cnl,icl}: Avoid static 8254 clock gating on S3 resume
This patch makes all legacy 8254 FSP UPDs (Enable8254ClockGating and Enable8254ClockGatingOnS3) depend on CONFIG_USE_LEGACY_8254_TIMER to avoid discrepancy between S0 and S3 resume flow. TEST=Able to boot to TianoCore without any hangs and errors, also verified S3 resume path doesn't clock gate 8254 timer using FSP-S UPD.
