Add support to parse the display configuration from device tree. If the board does not provide platform specific functions in the struct clcd_board contained with the amba device info, then defaults are provided by the driver. The device tree configuration can either ask for a DMA setup or provide a framebuffer address to be remapped into the driver. Signed-off-by: Ryan Harkin <redacted> ---

We are currently discussing a common panel description for the devicetree. You are invited to join in here: http://comments.gmane.org/gmane.linux.drivers.devicetree/21386 We shouldn't add any more device specific panel descriptions.
