[PATCH v2 13/14] rpmsg: virtio_rpmsg_bus: move back rpmsg_hdr into a public header

From: Suman Anna <s-anna@xxxxxx>

Commit e88dae5da46d ("rpmsg: Move virtio specifics from public header")
has moved the struct rpmsg_hdr definition from the public rpmsg.h and
made it private to virtio_rpmsg_bus module. This structure is a common
header used in all virtio rpmsg messages, and used by various virtio
rpmsg bus drivers. So, move this back into the virtio_rpmsg specific
public header to make it visible to various rpmsg drivers.
