ALSA: hda - Add reboot notifier
ALSA: hda - Add reboot notifier

The current snd-hda-intel driver seems blocking the power-off on some
devices like eeepc.  Although this is likely a BIOS problem, we can add
a workaround by disabling IRQ lines before power-off operation.
This patch adds the reboot notifier to achieve it.

The detailed problem description is found in bug#11889:
