Are you sure the compressed type is sensible?  It would normally only
make sense with a large number of closely packed registers but this
device has 8 bit register values.

What happens on non-DT systems?

Remove empty functions, though it's rather surprising that there's
nothing at all to do here..  Normally an MFD would at least remove its
children.
