xen: Fix xen-legacy-backend qdev types
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.

xen: cleanup unrealized flash devices
The generic pc_machine_initfn() calls pc_system_flash_create() which creates
'system.flash0' and 'system.flash1' devices. These devices are then realized
by pc_system_flash_map() which is called from pc_system_firmware_init() which
itself is called via pc_memory_init(). The latter however is not called when
xen_enable() is true and hence the following assertion fails:
qemu-system-i386: hw/core/qdev.c:439: qdev_assert_realized_properly:
Assertion `dev->realized' failed
These flash devices are unneeded when using Xen so this patch avoids the
assertion by simply removing them using pc_system_flash_cleanup_unused().
