The way the tile mode array index was calculated only makes sense for
the CIK specific macrotile mode array. For SI, we need to use one of the
tile mode array indices reserved for displayable surfaces.
This happened to result in correct display most if not all of the time
because most of the SI tiling modes use the same number of banks.

Thanks for doing this.

Thanks Alex.
Christian, can you cc stable when you pick this up?
Actually, I deliberately left that out, as the previous code mostly
seems to calculate the same result in practice, just not in the correct
way. So I'm not sure it's worth taking any risk for stable, however
small it may be. We can still nominate it for stable later if it turns
out to fix an actual problem in practice.
Anyway, I can't seem to find this patch in any DRM tree yet. Christian,
did you see it?
I've seen this patch, but somehow thought that it was for libdrm and not
the kernel module.
Nevermind I'm going to push it with the next drm-fixes.
Christian.
