The pixel clock determines how fast pixels can be processed. When adding non-native common modes, avoid adding modes that exceed the max pixel clock frequency of the native modes. Avoiding these avoids potential mode setting failures where the GPU can't handle the modeline since the configured pixel clock is too fast. This replaces the "bandwidth" check which used the number of pixels and refresh rate, which wasn't enough to avoid incompatible modes.
