With the generic omap3-u-boot.dtsi file available, this patch increased the memory of the various incarnations of the omap3_logic board, and points their respective u-boot.dtsi files to the newly created generic one, and removes the PLATDATA from the board file. These are all done at once because the're all utilizing the same omap3logic.c board file. Signed-off-by: Adam Ford <aford173@gmail.com>
