Right now, we have a lot of default device type options in the QEMUMachine
structure.  This is used by code within vl.c to determine whether it should
add classes of devices (like serial).

Really, vl.c has no business adding devices but all we need to do to support
this is create common machine options to describe whether there are default
devices of each class.  vl.c can then use that to determine whether to add
said devices.
