irqdomain: Add a fwnode_handle allocator
In order to be able to reference an irqdomain from ACPI, we need
to be able to create an identifier, which is usually a struct
device_node.
This device node does't really fit the ACPI infrastructure, so
we cunningly allocate a new structure containing a fwnode_handle,
and return that.
This structure doesn't really point to a device (interrupt
controllers are not "real" devices in Linux), but as we cannot
really deny that they exist, we create them with a new fwnode_type
(FWNODE_IRQCHIP).
