kconfig: modules: Trivial cleanup

A lot of the Kconfig stuff gets copied around, so encourage a clean
compact style:

 - Reduce license header spam

 - Fix some broken indentation

 - Turn a meaningless 'menuconfig' into a 'config'

 - Remove a redundant QMSI menu

 - Unscrunch comments: #Foo -> # Foo
