The pvrdma code relies on the pvrdma_ring.h kernel header for some
basic ring buffer handling. The content of that header isn't very
exciting, but contains some (q)atomic_*() invocations that (a)
cause manual massaging when doing a headers update, and (b) are
an indication that we probably should not be importing that header
at all.
Let's reimplement the ring buffer handling directly in the pvrdma
code instead. This arguably also improves readability of the code.
Importing the header can now be dropped.

cp_virtio is called for both the asm-s390/ and linux/ directories,
so it looks for pci_regs.h and input.h files in asm-s390/ too. This
makes little sense. In the next patch we will have the opposite
problem; we want to add asm-x86/hyperv.h, and there's also a
linux/hyperv.h file with unwanted dependencies on additional Linux
uapi headers. We do not want to copy linux/hyperv.h.
The solution is to make cp_virtio (now renamed to cp_portable) copy
one file only, instead of using the "find" command, and call it multiple
times. The new function is really just a reindentation of the old one.
