fdc: change auto fallback drive for ISA FDC to 288
The 2.88 drive is more suitable as a default because it can still read 1.44 images correctly, but the reverse is not true. Since there exist virtio-win drivers that are shipped on 2.88 floppy images, this patch will allow VMs booted without a floppy disk inserted to later insert a 2.88MB floppy and have that work. This patch has been tested with msdos, freedos, fedora, windows 8 and windows 10 without issue: if problems do arise for certain guests being unable to cope with 2.88MB drives as the default, they are in the minority and can use type=144 as needed (or insert a proper boot medium and omit type=144/288 or use type=auto) to obtain different drive types. As icing, the default will remain auto/144 for any pre-2.6 machine types, hopefully minimizing the impact of this change in legacy hw to basically zero.
