Ben's change merely adds a knob that a platform may set, in order to
enable the existing pata_platform driver, which is pretty safe by itself.
The next piece -- once not in 2.6.26 AFAIK -- is arch-specific code
selecting HAVE_PATA_PLATFORM. BAST IDE, I assume, can go away once
relevant platforms start turning on HAVE_PATA_PLATFORM.
