mfd: da9052: Fix genirq abuse
Rather than using the pointer passed back by the regmap API (or complaining because that wasn't actually being set) the da9052 driver was having some fun and games peering through genirq and regmap internals. Fix the driver to use the API as expected. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
