rpmsg: smd: Create device for all channels
Rather than selectively creating devices only for the channels that the remote have moved to "opening" state let's create devices for all channels found. The driver model will match drivers to the ones we care about and attempt to open these. The one case where this fails is if the user loads a firmware that lacks a particular channel of the previous firmware that was running, in which case we would find the old channel and attempt to probe it. The channel opening handshake will ensure this will result in a graceful failure. The result of this patch is that we will actively open the RPM channel even though it's left in a state other than "opening" after the boot loader's closing of the channel.
