fdc: Deprecate configuring floppies with -global isa-fdc

Browse source 
Deprecate

    -global isa-fdc.driveA=...
    -global isa-fdc.driveB=...

in favour of

    -device floppy,unit=0,drive=...
    -device floppy,unit=1,drive=...

Same for the other floppy controller devices.

This is -global instead of -device, because the floppy controller is
created automatically, and we want to configure that one, not create
a second one (which isn't possible anyway).
Without any -global isa-fdc,... you get an empty driveA and no
driveB. You can use -nodefaults to suppress the default driveA, see
