Once declared, you cannot access a linker_list entry since you do not have a symbol name for it. Add llsym() macro to provide this. This avoids searching for the symbol at run-time based on name.
An example usage is to declare a driver with U_BOOT_DRIVER(), then obtain a pointer to that driver later.
