hw/isa: specify instance_size in isa_superio_type_info

Right now all subclasses of TYPE_ISA_SUPERIO have to specify an instance_size,
because the ISASuperIODevice struct adds fields to ISADevice but the type does
not include the increased instance size.  Failure to do so results in an access
past the bounds of struct ISADevice as soon as isa_superio_realize is called.
Fix this by specifying the instance_size already in the superclass.
