[ARM] Update Acorn IDE drivers.

icside.c:
- Use C99 structure initialisers.
- Use generic DMA API.
- Use new hwif->hwif_data rather than hwif->hw.priv.
- Add DMA supported/dma supported masks.
- Remember the card type for the remove/shutdown methods.
- Add shutdown method.
rapide.c
- ecard_{claim,release} are no longer required.
