Saravana Kannan e2c1b0ff38 ARM: imx: avic: Convert to using IRQCHIP_DECLARE
Using IRQCHIP_DECLARE lets fw_devlink know that it should not wait for
these interrupt controllers to be populated as struct devices. Without
this change, fw_devlink=on will make the consumers of these interrupt
controllers wait for the struct device to be added and thereby block the
consumers' probes forever. Converting to IRQCHIP_DECLARE addresses boot
issues on imx25 with fw_devlink=on that were reported by Martin.

This also removes a lot of boilerplate code.

Fixes: e590474768 ("driver core: Set fw_devlink=on by default")
