[PATCH 19/27] mfd: remove ucb1400 support

From: Arnd Bergmann
Date: Thu Jan 05 2023 - 09:10:33 EST

From: Arnd Bergmann <arnd@xxxxxxxx>

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.
