But the reality tells that most chips need the buffer size alignment, and it'll be likely enabled in future, too. This patch drops AZX_DCAPS_ALIGN_BUFSIZE to give back one more previous DCAPS bit for future use. At the same time, rename AZX_DCAPS_BUFSIZE with AZX_DCAPS_NO_ALIGN_BUFSIZE for avoiding confusion. AZX_DCAPS_ALIGN_BUFSIZE are still kept (but commented out) in each DCAPS presets for a purpose as markers.
