arm64: dts: rockchip: Specify override mode for kevin panel
This patch adds an override mode for kevin devices. The mode increases both back porches to allow a pixel clock of 26666kHz as opposed to the 'typical' value of 252750kHz. This is needed to avoid interference with the touch digitizer on these laptops.
