[SeaBIOS] [PATCH] ramdisk: Allow ramdisk support (CONFIG_FLASH_FLOPPY) under QEMU

[Kevin O'Connor]

Don't require coreboot to use CONFIG_FLASH_FLOPPY - with the latest
QEMU, it's possible to place a floppy image into fw_cfg using the qemu
command line (eg, "-fw_cfg name=floppyimg/MyFloppy,file=file.img").
