I've got a pair of FA312 cards and this problem has bothered me
for ages.  This has finally prompted me to do something about it :)

Turns out that somebody wasn't following the documentation.  We were
doing 16-bit writes to 32-bit registers which led to some addresses
working and others not so lucky.

This patch should fix the problem.
