[PATCH 4/4] ARM: dts: rockchip: add Pinky board

While pinky was one of the earlier development models, is on the list
of endangered species today and nearly extinct, I want to keep mine
around for the foreseeable future after spending all the time making a
nice hole into the base below the dut-connector.
