ASoC: ak4375: Fix unused function error

A randconfig caught a compile warning that is now treated as a fatal
error:
  sound/soc/codecs/ak4375.c:415:13: error: ‘ak4375_power_off’ defined but not used [-Werror=unused-function]

where ak4375_power_off() is used only from the PM handler.

As both suspend and resumes are already marked with __maybe_unused,
let's rip off the superfluous ifdef CONFIG_PM, so that the error above
can be avoided.
