This commit broke Weston/KMS, and presumably also xf86-video-modesetting. In order to use Y-tiled buffers, the kernel requires the tiling mode to be explicitly named through the I915_FORMAT_MOD_Y_TILED AddFB2 modifier; it disallows any attempt to infer the buffer's tiling mode. As the GBM API does not have a way to extract modifiers for a buffer, this commit broke all users of GBM on SKL+. Revert it for now, until we get a way to extract modifier information from GBM, and also let GBM users inform the implementation that it intends to use the modifiers. This reverts commit 6a0d036483caf87d43ebe2edd1905873446c9589.
