ASoC: qcom: topology: Constify pointed snd_soc_tplg_dapm_widget

Several functions in topology.c receive pointers to 'struct
snd_soc_tplg_dapm_widget' and do not modify their contents.  Constify
the pointers for self-explanatory code (pointed memory is not modified
by the function) and a bit safer code.
