kconfig: link menus to a symbol
Currently, there is no direct link from (struct symbol) to (struct menu). It is still possible to access associated menus through the P_SYMBOL property, because property::menu is the relevant menu entry, but it results in complex code, as seen in get_symbol_str(). Use a linked list for simpler traversal of relevant menus. Signed-off-by: Masahiro Yamada <masahiroy@kernel.org> Reviewed-by: Nicolas Schier <nicolas@fjasle.eu>
