ide: remove CONFIG_IDEDMA_IVB config option 



Devices which don't set word 93 validation bit should be now handled by
ide-iops.c::ivb_list[] and for debugging purposes cable detection can be
completely overriden with "idex=ata66" parameter.

	---help---

	  There are unclear terms in ATA-4 and ATA-5 standards how certain

	  hardware (an 80c ribbon) should be detected. Different interpretations

	  of the standards have been released in hardware. This causes problems:

	  for example, a host with Ultra Mode 4 (or higher) will not run

	  in that mode with an 80c ribbon.



	  If you are experiencing compatibility or performance problems, you

	  MAY try to answer Y here. However, it does not necessarily solve

	  any of your problems, it could even cause more of them.



	  It is normally safe to answer Y; however, the default is N.
