[PATCH] remove config ordering/dependency between ucb1400-ts and sound subsystem

Browse Source 
Commit 2d4ba4a3b9 introduced a dependency
that was never meant to exist when the ac97_bus.c module was created.
Move ac97_bus.c up the directory hierarchy to make sure it is built when
selected even if sound is configured out so things work as originally
intended.
