Add priority field to rpmsg_endpoint structure to support message prioritization. This allows different endpoints to have different priority levels for scheduling purposes. Changes: - Define priority constants (MIN=0, DEFAULT=127, MAX=255) - Add RPMSG_PRIO_RT alias for real-time priority - Add priority field to struct rpmsg_endpoint - Initialize priority to default value in rpmsg_register_endpoint() Signed-off-by: Bowen Wang <wangbowen6@xiaomi.com>
