ASoC: cs35l41: Use modern pm_ops
Make use of the recently introduced EXPORT_GPL_DEV_PM_OPS() macro, to
conditionally export the runtime/system PM functions.

Replace the old SET_{RUNTIME,SYSTEM_SLEEP,NOIRQ_SYSTEM_SLEEP}_PM_OPS()
helpers with their modern alternatives and get rid of the now
unnecessary '__maybe_unused' annotations on all PM functions.

Additionally, use the pm_ptr() macro to fix the following errors when
building with CONFIG_PM disabled:

ERROR: modpost: "cs35l41_pm_ops" [sound/soc/codecs/snd-soc-cs35l41-spi.ko] undefined!
ERROR: modpost: "cs35l41_pm_ops" [sound/soc/codecs/snd-soc-cs35l41-i2c.ko] undefined!
