[PATCH] ACPI / PM: Do not save/restore NVS on Sony Vaio VGN-NW130D

[Rafael J. Wysocki]

From: Rafael J. Wysocki <rjw@xxxxxxx>

The saving of the NVS memory area during suspend and restoring it
during resume causes problems to appear on Sony Vaio VGN-NW130D, so
blacklist that machine to avoid those problems.

Hi Len,

Another Vaio needing acpi_sleep=nonvs, please apply.

Thanks,
Rafael
