mfd: AB3550 core driver

Browse Source 
This adds a core driver for the AB3550 mixed-signal circuit
found in the ST-Ericsson U300 platforms. This driver
is a singleton proxy for all access to the AB3550 sub
functionality drivers which can be added on top of this one:
RTC, regulators, battery and system power control, vibrator,
LEDs and an ALSA codec.

Select this to enable the AB3550 Mixed Signal IC core
functionality. This connects to a AB3550 on the I2C bus
and expose a number of symbols needed for dependent devices
to read and write registers and subscribe to events from
this multi-functional IC. This is needed to use other features
of the AB3550 such as battery-backed RTC, charging control,
LEDs, vibrator, system power and temperature, power management
and ALSA sound.
