armv6: enable over_n_8888

Enable the fast path added in the previous patch by moving the lookup
table entries to their proper locations.

Lowlevel-blt-bench benchmark statistics with 30 iterations, showing the
effect of adding this one patch on top of
"armv6: Add over_n_8888 fast path (disabled)", which was applied on
fd595692941f3d9ddea8934462bd1d18aed07c65.
