ARM: imx: Remove mx51_babbage board file
The device tree version for the babbage board (imx51-babbage.dtb) has a more complete support than the board file version, so remove the board file source code. Signed-off-by: Fabio Estevam <fabio.estevam@freescale.com> Signed-off-by: Shawn Guo <shawn.guo@freescale.com>
