ALSA: doc: Use DEFINE_SIMPLE_DEV_PM_OPS()topic/pm-ops
Use the new DEFINE_SIMPLE_DEV_PM_OPS() instead of SIMPLE_DEV_PM_OPS()
for the example code. This allows us to drop CONFIG_PM_SLEEP ifdefs.
While we're at it, expand the driver definition instead of passing
directly via .driver.pm field. This seems to be a more common
pattern.
