Revert "pcm/Convert: add option to enable the integer-only dsd2pcm implementation"

This reverts commit c84bae739a29ec27790c5534b7fc777d6f40a02f.  A
configuration option is not necessary, because the PcmConvert
constructor knows already whether integer or floating point is needed.

-DSD

-There are three ways to play back DSD (Direct Stream Digital):
-
-- natively if your output supports it (ALSA only and requires a sound
-  card with native DSD support)
-- `DSD over PCM <http://dsd-guide.com/dop-open-standard>`_: wrapped
-  inside fake 24 bit PCM samples (ALSA and OSX only and requires an
-  external DAC with DoP support)
-- for everything else, MPD automatically converts DSD to PCM
-
-For the last option, the setting ``dsd2pcm_converter`` selects a
-conversion method.  The default is ``float`` which converts to
-floating point samples.  For CPUs with a weak floating point unit
-(e.g. some ARMs like the one in the Raspberry Pi), it may be faster to
-use ``integer``, which is an integer-only implementation of the
-conversion algorithm.
