The cpu (de)tiler hw is gone, this stopped being useful. Plus it never
supported any of the fancy new tiling formats, which means userspace
also stopped using the magic side-channel this provides.
This would totally break a lot of the igts, but they're already broken
for the same reasons as userspace on gen12 would be.
