[PATCH 3/3] 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.
