[PATCH u-boot v2 08/38] linker_lists: declare lists and entries as __ADDRESSABLE for LTO

[Marek Behún]

Use the __ADDRESSABLE() macro to make entries and lists declared by
ll_entry_declare() and ll_entry_declare_list() addressable so that when
building with LTO the compiler does not optimize this data away.
