i386/pc_q35: don't insist on board FDC if there's no default floppy
The "no_floppy = 1" machine class setting causes "default_floppy" in
main() to become zero. Consequently, default_drive() will not call
drive_add() and drive_new() for IF_FLOPPY, index=0, meaning that no
default floppy drive will be created for the virtual machine. In that
case, board code should also not insist on the creation of the
board-default FDC.
The board-default FDC will still be created if the user requests a floppy
drive with "-drive if=floppy".
Additionally, separate FDCs can be specified manually with "-device
isa-fdc". They allow the
-device isa-fdc,driveA=...
syntax that is more flexible than the one required by the board-default
FDC:
-global isa-fdc.driveA=...
This patch doesn't change the behavior observably, as all Q35 machine
types have "no_floppy = 0".
