Qualcomm DSPs also supports the ALAC and APE decoders, so add support
for these and convert the snd_codec_params to qdsp format.

One minor nit, other that,

We should probably define this layout tag in asm.h
something like:

#define ALAC_CHANNEL_LAYOUT_TAG_Mono (100<<16) | 1
#define ALAC_CHANNEL_LAYOUT_TAG_STEREO (100<<16) | 2
