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.
