gpio/sodaville: Convert sodaville driver to new irqdomain API
The irqdomain api changed significantly in v3.4 which caused a build failure for this driver. Signed-off-by: Grant Likely <grant.likely@secretlab.ca> Acked-by: Sebastian Andrzej Siewior <bigeasy@linutronix.de> Cc: Hans J. Koch <hjk@linutronix.de> Cc: Torben Hohn <torbenh@linutronix.de>
