"git grep" says the only place we use our max7310 device is
on the "spitz" board. The point of removing all those
elderly Arm boards is that all this code is ancient and
unmaintained. If we were using this device on the imx6
boards I would have kept it, but we aren't. I don't want
to keep old, unmaintained, untested, dead code in the tree.
If anybody does want to use it on some board in future
they can always pull it out of the git history (and
check whether it needs work to bring it up to modern
standards, and write some tests for it...)
