Hmm, I do not prefer that this function be exported. It adds no value,
and this adds an asymmetric API for remoteproc drivers to add a mem
entry to the internal remoteproc lists, while relying on the remoteproc
core to remove them. The carveout list maintenance is a remoteproc
internal scheme, and so should be maintained that way. Further more, on
the current series, all the existing calls are immediately after a
rproc_of_resm_mem_entry_init() or a rproc_mem_entry_init() function,
which means this could very well be folded into those individual functions.
