soc/intel/apl: Configure LPC serial IRQ mode 

Sync the FSP settings with what coreboot does. Why both FSP and coreboot
configure this redundantly stays a secret.

TEST=Set SERIRQ_CONTINUOUS on kontron/mal10. A CPLD connected to LPC
     works correctly now, but was confused by the wrong settings before
     because the FSP defaults allowed to disable the LPC clock.
