[PATCH] Replace 0xff.. with correct DMA_xBIT_MASK

Browse source 
Replace all occurences of 0xff..  in calls to function pci_set_dma_mask()
and pci_set_consistant_dma_mask() with the corresponding DMA_xBIT_MASK from
linux/dma-mapping.h.

[Better use DMA_24BIT_MASK instead of 0x00ffffff.
See linux/include/dma-mapping.h for reference.]
When pci_set_dma_mask() is successful, and returns zero, the PCI layer
saves away this mask you have provided. The PCI layer will use this
