Furquan Shaikh 78a407f0a1 npcx: Set ESPI_MAXFREQ based on FMCLK value ...

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.
