[PATCH] Enable cdrom dma access with pdc20265_old

This patch allows me to use dma with my cd/dvd attached to my on board
pdc20265 ide controller

Alan sayeth:

  Looks sane.  Would be nice to know if there is any documentation
  supporting this hack being safe but the logic makes sense.  The LBA48 case
  faces the same problem - the state machine gets confused about the transfer
  length and needs kicking
