[PATCH] Last DMA_xBIT_MASK cleanups

These are the last conversions of pci_set_dma_mask(),
pci_set_consistent_dma_mask() and pci_dma_supported() to use DMA_xBIT_MASK
constants from linux/dma-mapping.h

 Finally, if your device can only drive the low 24-bits of
 address during PCI bus mastering you might do something like:
 
-	if (pci_set_dma_mask(pdev, 0x00ffffff)) {
+	if (pci_set_dma_mask(pdev, DMA_24BIT_MASK)) {
 		printk(KERN_WARNING
 		       "mydev: 24-bit DMA addressing not available.\n");
