[PATCH] remove config ordering/dependency between ucb1400-ts and sound subsystem
Commit 2d4ba4a3b9aef95d328d74a17ae84f8d658059e2 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.
