soc/intel/tigerlake: Correct IRQ interrupt
Current Interrupt setting use 2nd parameters as device function number.
- Correct as interrupt pin number according to _PRT package format.
{Address, pin, Source, Source index}
- Use irq number directly rather than irq definition as its number
is not for PCI device.
The issue found while enabling GBE and GBE interrupt is not working
without this change.
