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.
