[U-Boot] [PATCH 1/4] tegra2: Avoid warnings if CONFIG_SYS_TEXT_BASE is redefined.

[Thierry Reding]

If a board configuration file redefines CONFIG_SYS_TEXT_BASE, the U-Boot
build system will usually define it explicitly on the compiler command-
line, which will cause the define in tegra2-common.h to emit a
redefinition warning.

To allow boards to redefine CONFIG_SYS_TEXT_BASE, tegra2-common.h now
only defines CONFIG_SYS_TEXT_BASE when it isn't already defined by the
board configuration or the command-line respectively.
