[Fix] Disable certain power saving feature to keep the performance to output two 4K 60Hz monitors. [Test] Plug two 4K 60Hz and stare at the monitors. With the patch applied, no more flickers on the screen. [Where problems could occur] The GFX clock was restrained for stability on laptops. So if those laptops have ability to output to dual 4K 60Hz monitors, the systems can become unstable. However, Oland is really old chip, those laptops neither have 4K LVDS, nor have 4K capable HDMI/DP output.
