drm/i915: FDI link training broken on Ironlake by Ivybridge integration
Commit 357555c00f8414057f0c12ee3f479f197264123d split out IVB-specific
register definitions for FDI link training, but a piece of that commit
stopped executing some critical code on Ironlake systems while leaving
it running on Sandybridge.
Turn that code back on both Ironlake and Sandybridge
