x86: only compile floppy driver if CONFIG_ISA_DMA_API is enabled
The generic floppy disk driver utilizies the interface provided by
CONFIG_ISA_DMA_API, specifically claim_dma_lock(), release_dma_lock(),
request_dma(), and free_dma(). Thus, there's a strict dependency on the
config option and the driver should only be loaded if the kernel supports
ISA-style DMA.
