[PATCH v2] xillybus: XILLYBUS_OF should depend on HAS_DMA

[Geert Uytterhoeven <geert@linux-m68k.org>]

If NO_DMA=y:

    drivers/built-in.o: In function `xilly_of_unmap':
    xillybus_of.c:(.text+0xa860e): undefined reference to `dma_unmap_single'

    xillybus_of.c:(.text+0xa86ca): undefined reference to `dma_unmap_single'
    drivers/built-in.o: In function `xilly_dma_sync_single_for_device_of':
    xillybus_of.c:(.text+0xa8700): undefined reference to `dma_sync_single_for_cpu'
    drivers/built-in.o: In function `xilly_dma_sync_single_for_cpu_of':
    xillybus_of.c:(.text+0xa8726): undefined reference to `dma_sync_single_for_cpu'
