Amit Shah 17634ba255 virtio: console: Add a new MULTIPORT feature, support for generic ports
This commit adds a new feature, MULTIPORT. If the host supports this
feature as well, the config space has the number of ports defined for
that device. New ports are spawned according to this information.

The config space also has the maximum number of ports that can be
spawned for a particular device. This is useful in initializing the
appropriate number of virtqueues in advance, as ports might be
hot-plugged in later.

Using this feature, generic ports can be created which are not tied to
hvc consoles.

We also open up a private channel between the host and the guest via
which some "control" messages are exchanged for the ports, like whether
the port being spawned is a console port, resizing the console window,
etc.

Next commits will add support for hotplugging and presenting char
devices in /dev/ for bi-directional guest-host communication.

Rusty Russell 1dff399616 hvc_console: make the ops pointer const.
This is nicer for modern R/O protection.  And noone needs it non-const, so
constify the callers as well.

Rusty Russell 971f339000 virtio: console: statically initialize virtio_cons
That way, we can make it const as is good kernel style.  We use a separate
indirection for the early console, rather than mugging ops.put_chars.

We rename it hv_ops, too.
