[PATCH v2 08/24] mac_via: Fix to realize "mos6522-q800-via*" devices |

mac_via_realize() creates a "mos6522-q800-via1" and a
"mos6522-q800-via2" device, but neglects to realize them. Affects
machine q800.
In theory, a device becomes real only on realize. In practice, the
transition from unreal to real is a fuzzy one. The work to make a
device real can be spread between realize methods (fine),
instance_init methods (wrong), and board code wiring up the device
(fine as long as it effectively happens on realize). Depending on
what exactly is done where, a device can work even when we neglect
to realize it.
These two appear to work. Nevertheless, it's a clear misuse of the
interface. Even when it works today (more or less by chance), it can
break tomorrow.
Fix by realizing them right away.
