soc/intel/{skylake,cannonlake,icelake}: Correct GPIO IRQ start map

This implementation corrects the GPIO IRQ start map used for ITSS
polarity configuration. The lowest GPIO IRQ mapped in SKL/KBL, CNL,
and ICL is 24.

BUG=b:123315212
TEST=[TESTED on CNL-ONLY]
     Verify the ITSS polarity configuration for GPIOs are correctly
     getting restored to original coreboot configuration, after fsp-s
     call in itss_restore_irq_polarities() call.
