Currently there are two targets for the i.MX6SX SabreSD board: mx6sxsabresd_defconfig and mx6sxsabresd_spl_defconfig.

This brings additional maintainance effort without a clear advantage.

Keep only the mx6sxsabresd_defconfig one and remove mx6sxsabresd_spl_defconfig to keep it simpler.

Also remove the SPL related code from the board file.

Signed-off-by: Fabio Estevam festevam@gmail.com --- Changes since v1: - Also remove the SPL related code. (Peng)
