Main update from V4 [1] 
 - complete commit messages with Reviewed-by: Mathieu Poirier <mathieu.poirier@linaro.org>
 - rebased on kernel V.14-rc1.

This series can be applied and tested on "Linux 5.14-rc1"(e73f0f0ee754) branch

Series description:
This series is the second step in the division of the series [2]: 
"Introducing a Generic IOCTL Interface for RPMsg Channel Management".

The purpose of this patchset is to split the code related to the control
and the endpoint. The code related to the control part is moved in the rpmsg_ctrl.c.
This split is an intermediate step to extend the controls to allow user applications to
instantiate rpmsg devices.
    
Notice that this patchset does not modify the behavior for using the RPMSG_CREATE_EPT_IOCTL
and RPMSG_DESTROY_EPT_IOCTL controls.
  
The next step should be to add the capability to:
- instantiate rpmsg_chrdev from the remote side (NS announcement),
- instantiate rpmsg_chrdev from local user application by introducing the
  IOCTLs RPMSG_CREATE_DEV_IOCTL and RPMSG_DESTROY_DEV_IOCTL to instantiate the rpmsg devices,
- send a NS announcement to the remote side on rpmsg_chrdev local instantiation.
