ACPI: OSI: Remove Linux-Lenovo-NV-HDMI-Audio _OSI string

Browse Source 
This string was introduced because drivers for NVIDIA hardware
didn't handle HDMI properly.

This was fixed by commit b516ea586d ("PCI: Enable NVIDIA HDA
controllers"), so vendors shouldn't be using this string to modify
ASL any more.
