For POLICY_0, when a pipe only has a reader and no writer,
if the pipe is empty, set POLLHUP.
For POLICY_1, when a pipe only has a reader but no writer,
if the pipe is empty, POLLHUP will not be set.
This change corrects poll() behavior to match the two pipe policies.
No API changes.

Use rpmsg_send_offchannel_raw to fix stuck issue avoid getting stuck
when remote destroy ept.
When send messages from ap to android in Rptun thread, Android may
have sent NS_DESTROY through rpmsg_port and changed ept->dst to
RPMSG_ADDR_ANY in rpmsg_port_ns_callback; So rptun thread may be
stuck at this time because rpmsg_send detected dst_ept's dst_addr
is RPMSG_ADDR_ANY.
rpmsg_virtio_thread(rptun audio):
rpmsg_virtio_rx_callback -> rpmsg_router_cb -> rpmsg_send(dst_ept)
send to android
rpmsg_port_thread (android send NS_DESTROY):
rpmsg_port_ns_callback -> dst_ept->dest_addr = RPMSG_ADDR_ANY

Previously the ioctl-based configuration was not encoded properly.
It lacked the three command bits selecting the "set volatile
configuration" mode.
Thus, configuration the reference, power-down or gain resulted in no
change.
Now the configuration is properly applied.
The DAC value to be send is now combined with the proper command prefix
bits, too.
But this operation was already working, since the command prefix is zero.
