334a41ce9b mfd: Use dev_get_platdata()
Use the wrapper function for retrieving the platform data instead of
accessing dev->platform_data directly.

4b3b4a501d mfd: Fix for DA9055 driver initialization
This patch clears all the events received while powering up DA9055.

While powering up DA9055, both power sequencer and gpio events are received.
These events remain uncleared after boot up, due to which further event handling
also fails. DA9055 has three event registers. The event register bits are set
to '1' on receiving an event. The events can be cleared on writing a '1' to
the set bit, which would then clear that bit to '0'. After applying this patch
we have a clean state after boot up.

3cec5f4e75 mfd: da9055: Change irq state to default
This patch changes the irq state from high to the now default low.
Because the default PMIC irq state of DA9055 got changed from high to low.
This change should not affect any of the existing users since all of them
use active low state.

This patch has been tested on smdkv6410.
