[PATCH 2/4] ACPI: OSI: Remove Linux-Lenovo-NV-HDMI-Audio _OSI string

[Mario Limonciello]

This string was introduced because drivers for NVIDIA hardware
didn't handle HDMI properly.  This was fixed by commit b516ea586d71 ("PCI:
Enable NVIDIA HDA controllers"). So vendors shouldn't be using this
string to modify ASL anymore.
