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

Commit 2d4ba4a3 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.

This is used to avoid config and link hard dependencies between the
sound subsystem and other function drivers completely unrelated to
sound although they're sharing the AC97 bus. Concerned drivers
should "select" this.
