ALSA: hda - Clean up the code to check bdl_pos_adj option
Just a minor cleanup; instead of passing an array, pass the assigned bdl_pos_adj option value directory in struct azx. Also split the code to get the default bdl_pos_adj value for the change that will follow after this. Signed-off-by: Takashi Iwai <tiwai@suse.de>
