ASoC: SOF: remove const qualifier for 'struct snd_sof_dsp_ops'

Now that we start having multiple platforms with minor variants, the
use of the const qualifier for 'dsp_ops' is starting to be
sub-optimal: the structures are copied across platforms, with only a
couple of members that differ.

This patch removes the const qualifier without any functionality
changes, and adds an optional initialization callback. In follow-up
patches, the dsp_ops will revisited for Intel HDaudio platforms, with
the differences added programmatically over a common baseline.
