Jeff Epler c8f969feb5 samd: audio-dma: avoid memory allocations 
With the previous change, stereo mp3 playback changed from needing
4 2304-byte allocations to needing 2 4604-byte allocations.  This was
enough to cause MemoryErrors with regularity.

By using m_realloc() here, the existing memory region can be used.
m_realloc() also works on the first invocation, because m_realloc(NULL, sz)
just calls m_malloc of sz.

Jeff Epler cb6193bbc7 samd: When possible, use one DMA channel for stereo AudioOut 
.. the documentation doesn't make this clear, but in practice it works
to write both of the DATABUF registers at the same time.  This should
also reduce the amount of wear and tear DMA puts on the system, as the
number of transfers is cut in half.  (the number of bytes transferred
remains the same, though)

In principle, this could cover all stereo cases if audio_dma_convert_signed
also learned to 16-bit extend and swap values.  However, this is the
case that matters for stereo mp3 playback on PyGamer.

Testing performed: Listened to some tracks with good stereo separation.
