ALSA:hda: add alsa control for query of device

alsa control is added to facilitate querying dts decode capability of
connected device. dts decode capability of the connected device is
updated in the ELD buffer. That information is updated in the
ALSA control structure. In addition to that, the code is amended to
handle other pass through decoder mode support.
