[PATCH] uniwill: Add support for MECHREVO WUJIE Series 15 X Pro

[Yifei Yao]

 Add support for the MECHREVO WUJIE Series 15 X Pro (WUJIE
Series-X5SP4NAG).

I have tested the Uniwill features on my laptop: the RGB keyboard
backlight works correctly and supports a maximum brightness level of 4.
The secondary fan only starts when the system load and performance
level increase. AC auto boot and USB powershare also work correctly.
The Super key and CPU temperature reporting work correctly, with
temperatures reported in millidegrees Celsius.

This machine does not have an NVIDIA GPU; it uses an AMD GPU.
