This patch enables ADC filtering on UCB1400 codec by default. The
benefit from this change is mostly on some Colibri boards where
the ADCSYNC pin of the UCB1400 codec isn't connected causing the
touchscreen to jitter very badly. This change has no visible
effect on boards where the ADCSYNC pin is connected.
