[PATCH] ALSA: hda/realtek: Fix build error without CONFIG_PM

[Takashi Iwai <tiwai@xxxxxxx>]

The alc_spec.power_hook is defined only with CONFIG_PM, and the recent
fix overlooked it, resulting in a build error without CONFIG_PM.
Fix it with the simple ifdef.

We may drop the whole CONFIG_PM dependency there, but it should be
done in a separate cleanup patch later.

Fixes: 1e707769df07 ("ALSA: hda/realtek - Set GPIO3 to default at S4 state for Thinkpad with ALC1318")
