Add VFP timings for the non-VRR frame limiter, and enable content_driven HDR mode to workaround lack of Steam support for backlight control while the Go 2's panel is outputting PQ content. This can be re-assessed when Steam supports internal panels with HDR that behave less like the Steam Deck OLED when it comes to brightness adjustment.
…ss adjustment for Legion Go 2 As the launch window may come, rather than waiting a formal better fix, Lenovo prefer to make it work firstly. Thanks to Matte Schwartz's work on Legion Go 2, the script only changes the EOTF to gamma22. Once the fixes on gamescope and steam sides are done, this commit can be reverted and accept Matte Schwartz's original one.
