Patch for XPS 9560

I am facing the same problem on an XPS 9560 and had a look at the acpidump, here the corresponding check is as follows:

If ((OSYS <= 0x07D9) || ((OSYS == 0x07DF) && (_REV == 0x05)))

So, telling the BIOS that we support ACPI Rev. 5 should be sufficient for this model to allow powering down the Nvidia without locking up. There is already some code which does this for other XPS and Latitude models in drivers/acpi/blacklist.c, I extended it for the XPS 9560. I also sent the patch to the LKML.
