kconfig: add named choice group
As choice dependency are now fully checked, it's quite easy to add support for named choices. This lifts the restriction that a choice value can only appear once, although it still has to be within the same group, but multiple choices can be joined by giving them a name. While at it I cleaned up a little the choice type logic to simplify it a bit. Signed-off-by: Roman Zippel <zippel@linux-m68k.org> Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
