Subject: [PATCH 09/13] rpmsg: add override field in channel info

The override field is already used in the rpmsg_device.
This allows to force a service name to be associated to
a RPMsg service driver.
Adding this field in the channel info allows to force the channel
creation with a specified RPMsg service driver.
