[PATCH v2 v4.4.y-cip] ARM: dts: iwg20d-q7-common: Add LCD support


Marian-Cristian Rotariu
 

commit 6f89dd9e9325d05b1f54d860dbbc84b42aa40759 upstream.

The iwg20d comes with a 7" capacitive touch screen, therefore
add support for it.

(remove the LVDS decoder as there is no driver for it;
add panel timings to panel node since the LVDS driver reads them off the
panel DT node)
