[PATCH v9 07/11] rpmsg: Update rpmsg_chrdev_register_device function

From: Arnaud Pouliquen
Date: Mon Jan 24 2022 - 05:27:01 EST


The rpmsg_chrdev driver has been replaced by the rpmsg_ctrl driver
for the /dev/rpmsg_ctrlX devices management. The reference for the
driver override is now the rpmsg_ctrl.

Update the rpmsg_chrdev_register_device function to reflect the update,
and rename the function to use the rpmsg_ctrldev prefix.

The platform drivers are updated accordingly.
