[Nouveau] [PATCH 3/4] ACPI: OSI: Remove Linux-HPI-Hybrid-Graphics _OSI string

This string was introduced because drivers for NVIDIA hardware
didn't handle mux control properly.  This was fixed by commit 8e55f99c510f
("drm/i915: Invoke another _DSM to enable MUX on HP Workstation laptops").
So vendors shouldn't be using this string to modify ASL anymore.
