Make it easier to add compat properties, by
adding macros for properties duplicated across
machine types.
Note: there could be bugs in compat properties,
this patch does not attempt to address them,
the code is bug for bug identical to the original.
Tested by: generated a preprocessed file, sorted and
compared to sorted original.
Lightly tested on x86_64.

I've put the above on my branch as it's needed for
fixing balloon pci class. Let me know if there are
any objections.
