[PATCH v2 5/5] arm64: dts: rockchip: Specify override mode for kevin panel

[Sean Paul <seanpaul-F7+t8E8rja9g9hUCZPvPmw@public.gmane.org>]

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.

Changes in v2:
 - Wrap the timing in display-timings node to match binding (Rob/Thierry)
