I update 425e EVRX attachment a bit to make it use more
MI sti.c stuff efficiently (especially bus_space tags and handles,
MD softc no longer includes them).

Updated diffs are:
 https://gist.github.com/tsutsui/8560841f666ebe7866ab9e810a465a29
 (rev. 3)
Diffs against the first version:
 https://gist.github.com/tsutsui/011662baf7689e565ed1c95b26a3a77e

No visible differnece on Xorg and mlterm-wscons on 425e.

I'll commit this version soon.

Thanks,
