ALSA: hda: acpi: Use SYSTEM_SLEEP_PM_OPS()

The dev_pm_ops definition must be SYSTEM_SLEEP_PM_OPS() instead of
SET_SYSTEM_SLEEP_PM_OPS(); otherwise it leads compile warnings without
CONFIG_PM_SLEEP. The latest patch version I took was back to an old
macro (likely mistakenly), and I overlooked it at applying. Fix it
now.
