mfd: Delete ab3550 driver 

The AB3550 never passed the prototype stage. Instead it was used
as a precursor to AB5500 for testing basic building blocks used
in that chip, since they had large similarities. Since AB3550 will
not see the light of day in product form and since the prototypes
are no longer used, let's delete the driver and any references to
it.

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.
