ARM: OMAP: LDP: use new display drivers
Use new display drivers for LDP board. The new OMAP display drivers were merged for 3.11, and we can now change the board files to use the new ones and phase out the old ones. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com> Acked-by: Tony Lindgren <tony@atomide.com>
