Some SPL functions directly use the binman 'u_boot_any' symbols to get U-Boot's binman image position. These symbols are declared by the SPL/TPL_BINMAN_SYMBOLS configs, but they are accessed by macros defined by just CONFIG_BINMAN. So when BINMAN is enabled and BINMAN_SYMBOLS is disabled, the code tries to use undeclared symbols and we get an error.
Therefore, any use of 'u_boot_any' symbols in the code is an implicit dependency on SPL/TPL_BINMAN_SYMBOLS. However, in the current uses they are meant to be the next phase's values, where that happens to be U-Boot. In the meantime, helper funcions spl_get_image_pos/size() were introduced to get these values.
Convert all uses of u_boot_any symbols to these functions, so we only access these symbols at one place. Make sure they will not use these symbols when the BINMAN_SYMBOLS configs are disabled, by returning early in those cases.
