This pr adds support for the legion go. Right now, tdp modes and full fan speed work. Fan curves do not, and there is a lot of logging to dmesg.

Here is a log sample. The other WMI function seems like it is called incorrectly. In addition the fan curve buffer looks wrong.

The fan curve function though does match the WMI of the go. It just seems there is a buffer misalignment. I dont recall it being 88 bytes long.

Hm, maybe the GUID is different.

The GUID apear to be the right:
LLL driver line

Yeah the buffer read is too small. The new buffer interface is larger and contains temps too.

I fixed the wmi for the fan curves in the new laptops. However, it expects percentages, and the autoset function expects rpm. So the driver does not let me set the values.
