[PATCH] Use pci_set_dma_mask() instead of direct assignment of DMA mask

The amd8111e driver directly assigns the DMA mask to the dma_mask
member of the struct pci_dev instead of using pci_set_dma_mask(). This
makes the call to pci_dma_supported() redundant as pci_set_dma_mask()
does this check.

I do not own this device so I only compile-tested this patch.
