[Impact]
Some Dell systems crash when disabling Nvidia dGPU with I+N configurations
because Nvidia's driver does not supports RTD3.
[Fix]
BIOS added solutions with _OSI string "Linux-Dell-Video" to workaround RTD3,
and a patch to report _OSI("Linux-Dell-Video") is required in Linux kernel.
The patches are included in upstream and are cherry-picked from Linus's repo.
[Regression potential]
No regression as all but targeted firmware will not use this _OSI string
