  To: u-boot

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.

Changes since v1:
- Also remove the SPL related code. (Peng)
