ALSA: hda/cirrus - Simplify creation of new controls

Browse source 
This patch moves the mixer creation code in Cirrus codec driver from
its own build_controls callback to snd_hda_gen_add_kctl() for
simplification.

As a bonus, this allows us to remove the cs421x_build_controls as it
becomes identical with snd_hda_gen_build_controls().
