machine: Replace has_dynamic_sysbus with list of allowed devices

Browse source 
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.
