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.
