ASoC: ak4458: Convert to RUNTIME_PM_OPS() & co

commit 9f9c8e9 upstream.

Use the newer RUNTIME_PM_OPS() and SYSTEM_SLEEP_PM_OPS() macros
instead of SET_RUNTIME_PM_OPS() and SET_SYSTEM_SLEEP_PM_OPS() together
with pm_ptr(), which allows us dropping ugly __maybe_unused attributes
and CONFIG_PM ifdefs.

This optimizes slightly when CONFIG_PM is disabled, too.
