Subject: [PATCH 2/2] ARM: dts: da850: add a node for the LCD controller

From: Karl Beldan <kbeldan@...libre.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@...libre.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)]
