ALSA: cs4281: 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.
