soc/intel/meteorlake: Set DTT PCI device IRQ to INT_A/PIRQ_A
The Dynamic Tuning Technology (DTT) device IRQ is not programmable and
is INT_A/PIRQ_A (IRQ 16).
Reference: Meteor Lake U/H and U Type4 External Design Specification
External Design Document (657165)
TEST=Linux driver successfully uses IRQ 16 on rex. Without this patch
it was binding IRQ 18 but interrupts were going to IRQ 16.
