[U-Boot] [PATCH v4 5/7] imx6: add some flexibility for defining macros

[John Tobias]

iMX6 SabreSD has a different stack address (0x0093FFB8) compare
to the default stack address defined in the file.

The CONFIG_SYS_TEXT_BASE is defined in mx6sabre_common.h.
It is better to add the #ifndef to avoid compilation
warnings.
