TYPE_IOMMU_MEMORY_REGION is a direct subtype of TYPE_MEMORY_REGION.
Its instance struct is IOMMUMemoryRegion, and its first member is a
MemoryRegion. Correct. Its class struct is IOMMUMemoryRegionClass,
and its first member is a DeviceClass. Wrong. Messed up when commit
1221a47467 introduced the QOM type. It even included hw/qdev-core.h
just for that.
TYPE_MEMORY_REGION doesn't bother to define a class struct. This is
fine, it simply defaults to its super-type TYPE_OBJECT's class struct
ObjectClass. Changing IOMMUMemoryRegionClass's first member's type to
ObjectClass would be a minimal fix, if a bit brittle: if
TYPE_MEMORY_REGION ever acquired own class struct, we'd have to update
IOMMUMemoryRegionClass to use it.
Fix it the clean and robust way instead: give TYPE_MEMORY_REGION its
own class struct MemoryRegionClass now, and use it for
IOMMUMemoryRegionClass's first member.
Revert the include of hw/qdev-core.h, and fix the few files that have
come to rely on it.
