This patch focuses on adding the core rpmsg kernel infrastructure. The
next step, after getting the basic stuff in, would be adding rpmsg
drivers, and exposing user space API.

For some use cases, where userland talks directly with remote entities
(and otherwise requires no kernel involvement besides exposing the
transport), socket API is very nice as it's flexible and prevalent.

We already have several rpmsg drivers and a rpmsg-based socket API
implementation too, but we'll get to it only after the core stuff gets
in.

Thanks,
Ohad.
