[Fix] Read HDR meta to detect the max and min luminance. max_cll defines the content light luminance for individual pixel. max_fall defines frame-average level luminance. Use max_fall value instead of max_cll as a limit for brightness control. [Test] Verified on AMD Cezanne, Barcelo, Rembrandt and Intel ADL, also on LCD panel and OLED panel. The brightness is changed more obivously on OLED panel, and no affect on LCD panel. [Where problems could occur] Low risk, It may cause the max brightness can't be set. All 3 patches are in drm-misc tree.
