While it's very common to use RPMSG for communicating with firmware
running on these remoteprocs there is no functional dependency on RPMSG.
As such RPMSG should be selected by the system integrator and not
automatically by the remoteproc drivers.

This does solve problems reported with circular Kconfig dependencies for
Davinci and Keystone remoteproc drivers.
