include/hw/qdev-properties: Remove DEFINE_PROP_END_OF_LIST

Now that all of the Property arrays are counted, we can remove
the terminator object from each array. Update the assertions
in device_class_set_props to match.

With struct Property being 88 bytes, this was a rather large
form of terminator. Saves 30k from qemu-system-aarch64.

memory: Fix type of IOMMUMemoryRegionClass member @parent_class

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
1221a474676 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.

vga: disable global_vmstate for 3.0+ machine types

Move global_vmstate from vga_common_init() parameter to VGACommonState
field. Set global_vmstate to true for isa vga devices, so nothing
changes here. virtio-vga and secondary-vga already set global_vmstate
to false so no change here either. All other pci vga devices get a new
global-vmstate property, defaulting to false. A compat property flips
it to true for older machine types.

With this in place you don't get a vmstate section naming conflict any
more when adding multiple pci vga devices to your vm.
