ALSA: azt3328: Simplify 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.

This ends up with the allocation of a few additional bytes for the
register dumps even if it's not really used, but the code
simplification should justify the cost.
