[PATCH 10/11] version: Remove global macro U_BOOT_VERSION_STRING from version.h

[Pali Rohár]

Version string is available in global variable char version_string[].
Macro U_BOOT_VERSION_STRING is not used by any other file, so remove it
completely from version.h. Other files were already converted to use
variable version_string[].
