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 8e55f99 ("drm/i915: Invoke another _DSM
to enable MUX on HP Workstation laptops"), so vendors shouldn't be
using this string to modify ASL any more.
