[PATCH] ucb1400_ts depends SND_AC97_BUS

[PATCH] ucb1400_ts depends SND_AC97_BUS

This driver is an AC97 codec according to its help text.  However, if SOUND is
disabled, the "select SND_AC97_BUS" still inserts that into the .config file:

#
# Sound
#
# CONFIG_SOUND is not set
CONFIG_SND_AC97_BUS=m

Even if the config software followed dependency chains on selects, we should
try to limit usage of "select" to library-type code that is needed (e.g., CRC
functions) instead of bus-type support.
