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.

-          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.
