[PATCH] ARM: dts: sun5i: Utoo P66 add uart node and aliases

[Hans de Goede]

Like on most non devel-boards it is still possible to get an uart on
the Utoo P66 tablet by soldering some wires to the right pads on the PCB,
add support for this to the dts, like we do with all sunxi boards.

This one is no good, the uart cannot be used as it shares a pin with the
lcd-panel, self-NACK.
