ASoC: codecs: cs42l84: use snd_kcontrol_chip() instead of snd_soc_kcontrol_component()

We have very similar name functions (A)(B). Both gets component from
snd_kcontrol, but (A) is used in callback functions which is registered
through snd_soc_add_component_controls(), (B) is used through
snd_soc_dapm_new_widgets().

(A) snd_soc_kcontrol_component()
(B) snd_soc_dapm_kcontrol_component()

(B) is using very picky way to get component but using it is necessary in
ASoC. But (A) is just wrapper function to snd_kcontrol_chip(), and directly
using it without wrapper is very common way on ALSA.
To reduce confusions of similar function, let's use common way on (A).
