[U-Boot] [PATCH v3 4/8] imx6: add some flexibility for defining macros

[John Tobias]

iMX6 SabreSD has different stack address compare
to the default stack address defined on the file.

The CONFIG_SYS_TEXT_BASE is defined in mx6sabre_common.h which is
same address defined on file. At the same time to avoid compilation
warnings.
