Tim Wawrzynczak ed042a9687 soc/intel/tigerlake: Enable support for common IRQ block 
Since GPIO IO-APIC IRQs are fixed in hardware (RO registers), this patch
allows tigerlake 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.
