ALSA: als4000: Replace with DEFINE_SIMPLE_DEV_PM_OPS()

Use the	new DEFINE_SIMPLE_DEV_PM_OPS() instead of SIMPLE_DEV_PM_OPS()
for code-simplification.  We need no longer CONFIG_PM_SLEEP ifdefs.

For building properly, add the dummy functions for
snd_sbmixer_suspend/resume() functions, too.

Just a cleanup, no functional changes.
