Thanks. I was staring at the macro changes in ioport.h for too long...

It actually just needs 'struct resource' declared. I removed the
dependency on ioport.h, but it may make sense to leave the definition
of 'acpi_dev_gpio_irq_get_by()' here because non ACPI based systems
need a default implementation anyway.
