platform/x86: i2c-multi-instantiate: Introduce IOAPIC IRQ support
If ACPI table provides an Interrupt() resource we may consider to use it
instead of GpioInt() one.
Here we leave an error condition, when getting IRQ resource, to the driver
to decide how to proceed, because some drivers may consider IRQ resource
optional.
