Because the legacy Xen backend devices can optionally be plugged on the
TYPE_PLATFORM_BUS_DEVICE, have it inherit TYPE_DYNAMIC_SYS_BUS_DEVICE.
Remove the implicit TYPE_XENSYSDEV instance_size.
Untested, but I'm surprised the legacy devices work because they
had a broken instance size (QDev instead of Sysbus...), so accesses
of XenLegacyDevice fields were overwritting sysbus ones.

This then needs sysbus.h rather than qdev-core.h include.
Moreover, the patch in the reply needs to be inserted into the series before

Both are needed for the patch to compile.
