Subject: [PATCH] ARM: dts: imx25-pdk: native-mode is part of display-timings

Move the native-mode property inside the display-timings node.

According to
Documentation/devicetree/bindings/display/panel/display-timing.txt.
native-mode is a property of the display-timings node.

If it's located outside of display-timings, the native-mode setting is
ignored and the first display timing is used (which is a problem only if
someone adds another display timing).

Dear all,

I found this issue on a similar board when I tried to define two
variants that use different displays. I had two display timings and
ended up using the wrong one because native-mode was ignored outside of
display-timings.

Thanks for reviewing the patch,

Martin
