ALSA: hda - Fix possible compile warnings regarding CONFIG_PM
Replace with a proper ifdef check of CONFIG_PM_SLEEP in hda_intel.c. But other places in HD-audio driver are still marked with CONFIG_PM, since these can be called for power-saving even without CONFIG_PM_SLEEP. Signed-off-by: Takashi Iwai <tiwai@suse.de>
