Mina Almasry 73b3fc67a4 net: devmem: document that bind-tx is unprivileged by design
Unlike bind-rx, which configures shared NIC RX queues to steer incoming
traffic into the caller's dmabuf and requires CAP_NET_ADMIN
(uns-admin-perm), bind-tx only DMA-maps the caller's dmabuf so the caller
can transmit from it on their own sockets without affecting other traffic
or device configuration.

Add a comment in netdev.yaml and above netdev_nl_bind_tx_doit() to make it
explicit that NETDEV_CMD_BIND_TX is unprivileged by design.
