controllers to the command line as the code was moved to a place where
it's called per-disk.
Move the call back after formatting all disks and reiterate the disks to
find the floppy controllers.
This also moves the '-global' directive which sets up the default
ISA-FDC to the end after all the disks but since we are modifying the
properties it is safe to do so.
