The irq_base was used to map the nested interrupt numbers somewhere high
enough. twl6040 has one irq line towards the CPU (comes via
i2c_client->irq).
With this change we just change the mapping of the nested interrupt
range provided by twl6040 (instead of hardwired number we ask for
suitable range).
We have sdp4430 and PandaBoard with twl6040. They are fine. The other
non upstream boards should be fine as well with this change.
