mfd: remove ucb1400 support

The ucb1400 MFD driver and its gpio and touchscreen child
drivers were only used on a few PXA machines that were unused
for a while and are now removed.

Removing these leaves the AC97 support as ALSA specific,
no other drivers are now connected through this interface.

This enables support for the Philips UCB1400 touchscreen interface.
The UCB1400 is an AC97 audio codec. The touchscreen interface
will be initialized only after the ALSA subsystem has been
brought up and the UCB1400 detected. You therefore have to
configure ALSA support as well (either built-in or modular,
independently of whether this driver is itself built-in or
modular) for this driver to work.

module will be called ucb1400_ts.
