phy: intel: Fix for warnings due to EMMC clock 175Mhz change in FIP

Since the EMMC clock was changed from 200Mhz to 175Mhz in FIP,
there were some warnings introduced, as the frequency values
being checked was still wrt 200Mhz in code. Hence, the frequency
checks are now updated based on the current 175Mhz EMMC clock changed
in FIP.
