Kapil Porwal cca3c90ed9 soc/intel/meteorlake: Enable support for common IRQ block 
Since GPIO IO-APIC IRQs are fixed in hardware (RO registers), this patch
allows MTL boards to dynamically assign PCI IRQs. This means not relying
on FSP defaults, which eliminates the problem of PCI IRQs interfering
with GPIO IRQs routed to the same IRQ, when both have selected IO-APIC
routing.

BUG=none
TEST=Build and boot to google/rex. Check dmesg and make sure that there
is no regression.
