  rpmsg: char: Fix race between the release of rpmsg_eptdev and cdev (2022-01-17 16:39:58 -0600)

rpmsg fixes for v5.17-rc1

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.

The 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().
