ALSA: hda/realtek - Add path active flag
... and rewrite the initialization of output paths as a generic function that is applicable for both i/o directions. The new flag, active, is introduced to each nid_path entry. This indicates whether the given path is active, and it's used for checking whether a certain widget can be turned off or changed when a path is no longer used or newly enabled. It's still used only in the output paths. More wider adaption for input and loopback paths will be achieved in the later patch. Signed-off-by: Takashi Iwai <tiwai@suse.de>
