ALSA: aloop: add DSD formats

Browse Source 
The snd-aloop loopback driver does not modify or access the actual samples
in any way, defines no volume or mute controls, it's strictly bitperfect.
Therefore DSD formats can be supported without any modification.

Add all DSD formats to the list of supported formats.
