Cássio Gabriel b7feba842c ALSA: interwave: guard PM-only restore helpers with CONFIG_PM
The InterWave PM patch added snd_interwave_restore_regs() and
snd_interwave_restore_memory() as static helpers, but both are used only
from the resume path under CONFIG_PM.

On configurations without CONFIG_PM, such as alpha allyesconfig, this
leaves both helpers unused and triggers -Wunused-function warnings with
W=1.

Move the PM-only helpers into the existing CONFIG_PM section. Keep
__snd_interwave_restore_regs() outside the guard because it is also used
during probe-time initialization.
