net: pasemi: set a 64-bit DMA mask on the DMA device
The pasemi driver never set a DMA mask, and given that the powerpc
DMA mapping routines never check it this worked ok so far. But the
generic dma-direct code which I plan to switch on for powerpc checks
the DMA mask and fails unsupported mapping requests, so we need to
make sure the proper 64-bit mask is set.
