I've no problem with removing support for the z1 stepping from the
kernel.  However, I don't think we should erase it from binding docs.
I'm not sure what the DT maintainers think is the appropriate action
here, but I'm thinking we could add a 'Deprecated' section at the end of
the doc and move these hunks there.  With a little rewording of course.

I'm primarily concerned about users with older dtbs looking to upgrade,
"Hey, wtf is marvell,armada375-z1-thermal?  I looked in the binding docs
and there's nothing there, do I replace it with marvell,armada375-thermal?"

thx,

Jason.
