This function probably belongs to pci layer. Put it in libata with
pci_test_bits() for the time being.
AFAIK the default DMA mask is always 32-bit. Code (often written by me)
that sets it to a 32-bit mask was just paranoia, and not really needed.
Hence, the pci_go_64() function I added, found in #upstream.
