The existing has_dynamic_sysbus flag makes the machine accept every user-creatable sysbus device type on the command-line. Replace it with a list of allowed device types, so machines can easily accept some sysbus devices while rejecting others. To keep exactly the same behavior as before, the existing has_dynamic_sysbus=true assignments are replaced with a TYPE_SYS_BUS_DEVICE entry on the allowed list. Other patches will replace the TYPE_SYS_BUS_DEVICE entries with more specific lists of devices. Cc: Peter Maydell <peter.maydell@linaro.org> Cc: Marcel Apfelbaum <marcel@redhat.com> Cc: "Michael S.
