2.6.27.59-stable review patch. If anyone has any objections, please let us
know.
DMA support was added to this driver only in 2.6.29, hence this patch is
not needed in 2.6.27.y...

commit 77c5fd19075d299fe820bb59bb21b0b113676e20 upstream.
pata_mpc52xx supports BMDMA but inherits ata_sff_port_ops which
triggers BUG_ON() when a DMA command is issued. Fix it.
