rtl8180: change PCI DMA mask to DMA_BIT_MASK(32)
From the original report: "I had problems to get my rtl8185 PCI card running on Sparc64: I always got an error about "No suitable DMA available" followed by an error that no device could be detected. When comparing the rtl8180 driver to others I noticed that others are mostly using DMA_BIT_MASK so I changed the custom mask to DMA_BIT_MASK(32) which fixed my issue."
