SysBus EHCI was introduced in a hurry before 1.3 Soft Freeze. To use QOM casts in place of DO_UPCAST() / FROM_SYSBUS(), we need an identifying type. Introduce generic abstract base types for PCI and SysBus EHCI to allow multiple types to access the shared fields. The VMSTATE_PCI_DEVICE() macro does not play nice with the QOM parent_obj naming convention, so defer that cleanup.
