ALSA: hda/ca0132: constify templates for control element set

Browse Source 
An array of templates for control element set is passed as an
argument for snd_hda_add_new_ctls(). This argument has 'const'
qualifier therefore the passed array can have the qualifier.

This commit adds this optimization.
