When using the 'simple' handler as a chained handler, the end hook
should be called so the chained handler can properly ack/unmask
etc. after the threaded handler has completed.
In particular, the chained GPIO IRQ hander on OMAP uses the 'simple'
handler since the GPIO IRQs can be dynamically configured either as
edge or level. When using threaded IRQs, the only way to know when
the handler is done and do the proper ack/unmask is via the end hook.
