[PATCH 12/12] vt82c686: Do not add floppy

[BALATON Zoltan]

The floppy is inaccessible because its ports are shadowed by the
config registers of the superio part (switchable on the real chip but
we don't model that) so disable adding the floppy matching the
existing comment in vt82c686b_isa_realize() as it's not usable.
