ALSA: seq: Reorganize kconfig and build
This is a slightly intensive rewrite of Kconfig and Makefile about ALSA sequencer stuff. The first major change is that the kconfig items for the sequencer are moved to sound/core/seq/Kconfig. OK, that's easy. The substantial change is that, instead of hackish top-level module selection in Makefile, we define a Kconfig item for each sequencer module. The driver that requires such sequencer components select exclusively the kconfig items. This is more straightforward and standard way. Signed-off-by: Takashi Iwai <tiwai@suse.de>
