[PATCH v2] ALSA: compress: Add SND_AUDIOCODEC_BESPOKE

[Charles Keepax <ckeepax@opensource.wolfsonmicro.com>]

When working with the compressed framework occasionally vendors will
use esoteric internal audio formats. For such formats it doesn't really
make sense to add an new define to the kernel as their use is not
sufficiently general.

This patch adds a new define SND_AUDIOCODEC_BESPOKE that vendors can use
in such situations.

Changes since v1:
 - Added a comment to note that users of BESPOKE are free to use the
   reserved space in snd_enc_generic.

Thanks,
Charles
