This one matches libdrm in using 16 for the tile height alignment on
gen2.

If there's a stricter alignment requirement, then we must fix both the
2D driver and libdrm. Otherwise, the user's session will simply crash at
startup.

However, I still see absolutely no evidence that gen2 requires tile
alignment to 32 rows, or that gen3+ requires tile alignment to 16
rows in any software configuration at all.
