soc/intel/cannonlake: Use new IRQ module
Since GPIO IO-APIC IRQs are fixed in hardware (RO registers), this patch allows cannonlake 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. Also prodrive/hermes (intel/cannonlake) was the only user of uart_acpi_write_irq(), therefore use the allocated IRQ instead of the fixed IRQ number in that function to preserve behavior.
