bbswitch: Support for legacy _DSM function
...
Newer Optimus laptops seems to use a _DSM method which is quite standard. This
is referred to as "Optimus DSM" in some DSDT files and must be called before the
discrete nVidia graphics card is turned off. Other (older?) laptops use a
different UUID, revision ID and arguments which actually enables or disables a
device. The right _DSM arguments is detected during the module initialization.
