Subject: [PATCH] remoteproc: export rproc re/unregister to virtio device APIs

In some case, the remote processor already boot up on previous state,
but still need register to virtio device, so that exported those APIs.

Hi

In our case, the remote processor is already boot up in u-boot,
we don't want to boot again or load fw in driver but register to virtio
device for rpmsg. so that needs those API exported.
Furthermore, the rproc_vq_interrupt is exported, so those functions
should be exported also.

thanks
