ASoC: codecs: pcm3168a: Prevent regulator double-disable in S4

Browse Source 
The SLEEP_PM_OPS are unset for the driver. Hibernation (S4) causes no
resume (skipped thanks to smart_suspend=true) yet still performs the
suspend sequence unconditionally, see device_complete() in
drivers/base/power/main.c.

If S4 runs for already suspended pcm3168a device, we end up with
"unbalanced disables" warning from the regulators. Assigning the
operations fixes the problem.
