Pull rpmsg fixes from Bjorn Andersson:
 "The cdev cleanup in the rpmsg_char driver was not performed properly,
  resulting in unpredicable behaviour when the parent remote processor
  is stopped with any of the cdevs open by a client.

  Two patches transitions the implementation to use cdev_device_add()
  and cdev_del_device(), to capture the relationship between the two
  objects, and relocates the incorrectly placed cdev_del()"
