It does create possible errors, since it is possible to choose config
options which won't compile.
The fact that defconfig have this option enabled for those platforms
does not matter. What matters is that I can then validly change the
config with make menuconfig, and it won't compile. A compilation error
should not occur with valid config options. That's why dependencies
need to be made in Kconfig, so that if Kconfig decides that kwbimage is
to be built, then it will force crypto.
(Yes, I know that there currently are many ways to change Kconfig
options and the result will fail to compile. That behaviour is
unwanted and should be fixed by adding Kconfig dependencies so that it
isn't possible to choose configuration that won't compile.)
