According to NPCX data sheets (NPCX5 and NPCX7), ESPI_MAXFREQ should be decided based on the value of FMCLK. Since we are setting FMCLK to 30MHz on NPCX5, eSPI_MAXFREQ needs to be set to 33MHz. This change sets ESPI_MAXFREQ_MAX depending upon the value of FMCLK. BUG=b:73504527 BRANCH=fizz? TEST=Verified that on soraka ESPI_MAXFREQ is set to 33MHz. Also, ran some reboot tests to ensure that there is no regression in boot time.
