[PATCH] kconfig: Clarify menu and 'if' dependency propagation

[Ulf Magnusson]

It is not obvious that the last two cases refer to menus and ifs,
respectively, in the conditional that sets 'parentdep'.

Automatic submenu creation is done later, so the parent can't be a
symbol here.

No functional changes. Only comments added.
