memory_region_init*() takes an @owner argument that becomes the QOM parent of the MemoryRegion object. When NULL is passed the region is silently reparented under /machine/unattached, hiding its lifetime owner.
Convert trivial owner==NULL sites in board init functions and device realize functions across small subdirectories. The owner is the enclosing machine or device in every case: hw/hexagon OBJECT(machine|ms|vms) virt, hexagon_dsp hw/hppa parent, OBJECT(machine) hw/ipmi OBJECT(ii) IPMIInterface implementations hw/loongarch OBJECT(machine) hw/microblaze OBJECT(machine) hw/or1k OBJECT(machine) hw/pci-host OBJECT(dev) bonito realize hw/rtc OBJECT(dev) ls7a realize hw/sparc OBJECT(machine) hw/sparc64 OBJECT(machine) hw/vmapple OBJECT(vms) hw/xen OBJECT(s) xen-pvh-common ram init No functional change: memory_region_do_init() would have parented these under /machine/unattached; they now sit under their creator.
