arm64: dts: rockchip: add overlay for RockPro64 screen

Browse source

The Pine64 touch panel is a panel consisting of the Feiyang fy07024di26a30d
panel with a Goodix gt911 touch screen. Add a device tree overlay to
allow the display to be easily used on the device.

This was previously included in the main device tree but left disabled
by default which still required rebuilding the DT to use the device, now
overlays can go upstream the overlay is the best way to handle the
add on devices.
