[ALSA] hdspm - Support for Master mode of AES32 and recent MADI

The current MADI driver was found not to completely work, at least on recent
MADI cards (rev 204), in particular at 96kHz. This patch solves this:
  * Add support of DDS feature
  * Channel map fixed
  * Channel/rate rules fixed
  * DMA allocation fixed (need to alloc for all channels and not only for the
    used ones)
Full support for AES32 master mode was added:
  * Add support of DDS feature
  * Channel map fixed
  * Channel/rate rules fixed
