Markus Armbruster 99ba777e53 qdev: Convert uses of qdev_set_parent_bus() with Coccinelle
In addition to the qdev_create() patterns converted so far, we have a
qdev_set_parent_bus() pattern.  Mostly when we embed a device in a
parent device rather than allocating it on the heap.

This pattern also puts devices in the dangerous "no QOM parent, but
plugged into bus" state I explained in recent commit "qdev: New
qdev_new(), qdev_realize(), etc."

Apply same solution: convert to qdev_realize().  Coccinelle script:

    @@
    expression dev, bus, errp;
    symbol true;
    @@
    -    qdev_set_parent_bus(DEVICE(dev), bus);
         ...
    -    object_property_set_bool(OBJECT(dev), true, "realized", errp);
    +    qdev_realize(DEVICE(dev), bus, errp);

    @ depends on !(file in "qdev-monitor.c") && !(file in "hw/core/qdev.c")@
    expression dev, bus, errp;
    symbol true;
    @@
    -    qdev_set_parent_bus(dev, bus);
         ...
    -    object_property_set_bool(OBJECT(dev), true, "realized", errp);
    +    qdev_realize(dev, bus, errp);

    @@
    expression dev, bus;
    symbol true;
    @@
    -    qdev_set_parent_bus(DEVICE(dev), bus);
         ...
    -    qdev_init_nofail(DEVICE(dev));
    +    qdev_realize(DEVICE(dev), bus, &error_fatal);

Unconverted uses of qdev_set_parent_bus() remain.  They'll be
converted later in this series.
