ASoC: msm: qdsp6v2: Fix bit alignment in snd_codec params

Pointer member variables in snd_codec params break bit alignment and
causes data corruption. By changing these pointers to fixed size
array variables, the bit alignment is rectified. The size has been
set to max possible size. Also, remove params which are not required
anymore.
