usb-bot: hotplug support
This patch marks usb-bot as hot-pluggable device, makes attached
property settable and turns off auto-attach in case the device
was hotplugged.
Hot-plugging a usb-bot device with one or more scsi devices can be
done this way now:
(1) device-add usb-bot,id=foo
(2) device-add scsi-{hd,cd},bus=foo.0,lun=0
(2b) optionally add more devices (luns 0 ... 15).
(3) qom-set foo.attached = true
