Uwe Kleine-König 9e2726776d mfd: Near complete mc13783 rewrite
This fixes several things while still providing the old API:

 - simplify and fix locking
 - better error handling
 - don't ack all irqs making it impossible to detect a reset of the
   rtc
 - use a timeout variant to wait for completion of ADC conversion
 - provide platform-data to regulator subdevice (This allows making
   struct mc13783 opaque for other drivers after the regulator driver is
   updated to use its platform_data.)
 - expose all interrupts
 - use threaded irq

After all users in mainline are converted to the new API, some things
(e.g. mc13783-private.h) can go away.
