ieee1394: revert "sbp2: enforce 32bit DMA mapping"
Revert commit 0555659d63c285ceb7ead3115532e1b71b0f27a7 from 2.6.22-rc1.
The dma_set_mask call somehow failed on a PowerMac G5, PPC64:
http://lkml.org/lkml/2007/8/1/344
Should there ever occur a DMA mapping beyond the physical DMA range, a
proper SBP-2 firmware will report transport errors. So let's leave it
at that.
