kconfig-language.txt: remove bogus hint
For the use case the hint describe a simple dependency is enough. Signed-off-by: Adrian Bunk <bunk@kernel.org> Acked-by: Randy Dunlap <randy.dunlap@oracle.com>

limits FOO to module (=m) or disabled (=n).
-Build limited by a third config symbol which may be =y or =m
-A common idiom that we see (and sometimes have problems with) is this:
-When option C in B (module or subsystem) uses interfaces from A (module
-or subsystem), and both A and B are tristate (could be =y or =m if they
-were independent of each other, but they aren't), then we need to limit
-C such that it cannot be built statically if A is built as a loadable
-module. (C already depends on B, so there is no dependency issue to
-take care of here.)
-If A is linked statically into the kernel image, C can be built
-statically or as loadable module(s). However, if A is built as loadable
-module(s), then C must be restricted to loadable module(s) also. This
-can be expressed in kconfig language as:
-config C
- depends on A = y || A = B
-or for real examples, use this command in a kernel tree:
-$ find . -name Kconfig\* | xargs grep -ns "depends on.*=.*||.*=" | grep -v orig
