Now we have more than 99% machines work well with current i8042 code
path, and less than 1% of machines (those MSI Wind & clones) that
don't work unless being added to this list.

If we do multiple-resetting unconditionally (for all machines), we are
1. fixing things that works well
2. make >99% machines (the good citizens) untested

This seems a change too aggressive for me. Do we have a good reason
for taking this risk?

Of course if we found the "actual problem" we'd conjure up a better
fix. But before that, I'd prefer the conservative way.
