remove dma and ioport kcms + remainder of base infrastructure

a couple weeks ago we were briefly musing on this topic on Matrix but couldn't really find a solid use case for these kcms KCMs as the chance of a user wanting or needing to know dma or ioport info is quickly approaching zero, even as far as diagnostics go they are very far out there.

since they are the only thing holding up removal of the os base infrastructure we'll drop the modules along with the remainder of the base code.

if we found need for them again they should be easy enough to make from scratch using the cli infrastructure instead. there's zero code reuse potential for cli based modules either way.
