snd_soc_tplg_component_load() does not modify its "*ops" argument. It only read some values and stores it in "soc_tplg.ops". This argument and the ops field in "struct soc_tplg" can be made const. Signed-off-by: Christophe JAILLET <christophe.jaillet@wanadoo.fr>
Constifying "struct snd_soc_tplg_ops" moves some data to a read-only section, so increase overall security.

Now that the soc-topology can handle "const struct snd_soc_tplg_ops" make sure that new usages of the struct already enter the tree as const. Signed-off-by: Christophe JAILLET <christophe.jaillet@wanadoo.fr>
