[PATCH v2 3/3] ASoC: fsl: fsl_xcvr: Switch to RUNTIME_PM_OPS()

[Fabio Estevam <festevam@xxxxxxxxx>]

From: Fabio Estevam <festevam@xxxxxxx>

Replace SET_RUNTIME_PM_OPS() with its modern alternative RUNTIME_PM_OPS().

The combined usage of pm_ptr() and RUNTIME_PM_OPS() allows the
compiler to evaluate if the runtime suspend/resume() functions are used
at build time or are simply dead code.

This allows removing the __maybe_unused notation from the runtime
suspend/resume() functions.
