Subject: [PATCH 9/9] [DO NOT MERGE] ARM: dts: sun6i: Enable 7" LCD panel on Sinlinx SinA31s

Sinlinx SinA31s comes with an optional 7" 1024x600 LCD panel with
capacitive touch panel that bolts on to the board.

Enable the display using a panel with close timings. This patch is more
of a proof of concept. The LCD panel has no markings whatsoever, and
the timings are not exactly the same, and as a result the display produces
glitch lines sometimes.
