soc/intel/cnl: Sync CONFIG_LPSS_UART_FOR_CONSOLE with FSP

We got rid of the dangerous reconfiguration of arbitrary pads in
coreboot, but FSP still overrode that. Make sure that it doesn't
enable a UART for debug output when it isn't configured in core-
boot.

This, again, shows how dangerous it is to leave any FSP UPD at
its binary default.
