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.
