ASoC: tegra20: Convert to RUNTIME_PM_OPS() & co

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.

This optimizes slightly when CONFIG_PM is disabled, too.
