edid-decode: output full frequencies for 4:2:0
Don't half hfreq for 4:2:0 timings - the character clock is halved, but the number of characters per line is also halved (two luminance values per character for 4:2:0), so there's no change in hfreq. Don't half pixel clock because it looks weird. Character clock is halved but the number of pixels remains the same (two luminance values per character for 4:2:0). Continue to use the half hfreq and half pixel clock for the ranges calculations because some non-HDMI 2.0 displays have max pixel clock halved when they have 4:2:0 modes and because other reasons that lead to adding this code in the first place?
