Enabling CONFIG_BINMAN makes binman run after a build to package any images specified in the device-tree. It also enables a mechanism for SPL/TPL to declare and use special linker symbols that refer to other entries in the same binman image. A similar feature that gets this info from the device-tree exists for U-Boot proper, but it is gated behind a CONFIG_BINMAN_FDT unlike the symbols. Confusingly, CONFIG_SPL/TPL_BINMAN_SYMBOLS also exist. These configs don't actually enable/disable the symbols mechanism as one would expect, but declare some symbols for U-Boot using this mechanism. Reuse the BINMAN_SYMBOLS configs to make them toggle the symbols mechanism, and declare symbols for the U-Boot phases in a dependent BINMAN_UBOOT_SYMBOLS config. Extend it to cover symbols of all phases. Update the config prompt and help message to make it clearer about this. Fix binman test binaries to work with CONFIG_IS_ENABLED(BINMAN_SYMBOLS).
