[ Upstream commit 98829e84dc67630efb7de675f0a70066620468a3 ] In Windows the ASUS Armory Crate program can enable or disable the dGPU via a WMI call. This functions much the same as various Linux methods in software where the dGPU is removed from the device tree. However the WMI call saves the state of dGPU (enabled or not) and this then changes the dGPU visibility in Linux with no way for Linux users to re-enable it. We expose the WMI method so users can see and change the dGPU ACPI state. Signed-off-by: Luke D.
