[RFC PATCH u-boot 03/12] linker_lists: declare entries and lists externally visible

[Marek Behún]

Use the `__visible` macro to declare entires and lists declared by
ll_entry_declare() and ll_entry_declare_list() externally visible, so
that when building with LTO the compiler does not optimize this data
away.
