I dunno, do we want (potentially a bunch of) platform specific
defconfigs? I'd sooner delete the ones that we have than add more!
I would suggest to just turn on NONPORTABLE, but that isn't a solution
given that the RZ/Five support requires turning off Zicbom. Ultimately I
think it is Palmer's decision whether we add a defconfig for the
platform - it is a bit of a special case given the aforementioned
incompatibility.
