This patch introduces acpi_unregister_irq function to free a linux IRQ number<->GSI mapping by a given linux IRQ number.
Even we have successfully registered the GSI, when some error occurs, we may need to unmap it for freeing the IRQ resource. But in some cases, we only have IRQ, but not GSI.
This patch is the preparation for memory-mapped timer support in GTDT driver.

This will need comments/acks from the ACPI folk.
I've now reworked the cleanup to not require this API, and will drop this patch.
Thanks, Mark.
