pluart(4) does not report the correct baudrate for the hardware console

but instead defaults to 38400. This in turn causes the same baudrate to
end up in /etc/ttys during installation. Note that this is not a problem
as of now since pluart does not support changing the baudrate just yet.

Instead, honor and propagate the baudrate given to pluartcnattach()
while attaching the hardware console.
