Subject: [PATCH 13/13] kconfig: change "modules" from sub-option to first-level attribute
Now "modules" is the only member of the "option" property.
Remove "option", and move "modules" to the top level property.

-- misc options: "option" <symbol>[=<value>]

- Various less common options can be defined via this option syntax,
- which can modify the behaviour of the menu entry and its config
- symbol. These options are currently possible:
-
- - "modules"
- This declares the symbol to be used as the MODULES symbol, which
- enables the third modular state for all config symbols.
- At most one symbol may have the "modules" option set.
