xen-sysdev is a TYPE_SYS_BUS_DEVICE. bus_type should not be changed so
that it can plug into the System bus. Otherwise this assert triggers:
qemu-system-i386: hw/core/qdev.c:102: qdev_set_parent_bus: Assertion
`dc->bus_type && object_dynamic_cast(OBJECT(bus), dc->bus_type)'
failed.
TYPE_XENBACKEND attaches to TYPE_XENSYSBUS, so its class_init needs to
be set accordingly to attach the qdev. Otherwise the following assert
triggers:
qemu-system-i386: hw/core/qdev.c:102: qdev_set_parent_bus: Assertion
`dc->bus_type && object_dynamic_cast(OBJECT(bus), dc->bus_type)'
failed.
TYPE_XENBACKEND is not a subclass of XEN_XENSYSDEV, so it's parent
is just TYPE_DEVICE. Change that.
