This patch makes the build system link the console framework code by default, like it already does with other common libraries (e.g. cache helpers). This should not make a difference in practice since TF is linked with --gc-sections, so the linker will garbage collect all functions and data that are not referenced by any other code. Thus, if a platform doesn't want to include console code for size reasons and doesn't make any references to console functions, the code will not be included in the final binary. To avoid compatibility issues with older platform ports, only make this change for the MULTI_CONSOLE_API.
