[VirtIO] Disable support for dynamic creating endpoint

OpenAMP_Init accepts rpmsg_ns_bind_cb, however, this Arduino
Core will not allow dynamic endpoint (VirtSerial) creation, but
only support dynamic binding endpoints that are already created
by VirIOSerial.begin().

Therefore just remove such parameters seems more appropriate.
