[PATCH] drivers/net/wireless/ipw2200: Use the DMA_32BIT_MASK constant

Use the DMA_32BIT_MASK constant from dma-mapping.h when calling
pci_set_dma_mask() or pci_set_consistent_dma_mask() instead of custom macros.

This patch includes dma-mapping.h explicitly because it caused errors on some
architectures otherwise.  See
