From: Karl Beldan <kbeldan@baylibre.com>

Add pins used by the LCD controller and a disabled LCDC node to be
reused in device trees including da850.dtsi.

Signed-off-by: Karl Beldan <kbeldan@baylibre.com>
[Bartosz:
- added the commit description
- changed the dt node name to a generic one
- added a da850-specific compatible string
- removed the tilcdc,panel node
- moved the pins definitions to da850.dtsi as suggested by
Sekhar Nori (was in: da850-lcdk.dts)]
