No specific need... It is confusing but it is the same as with
regulators. The parent MFD driver creates children devices and match
drivers. The children (e.g. clk or regulator driver) look for hard-coded
subnode - clocks/regulators.
The compatible is actually not used in current form.

That is partially my fault. I got convinced by Lee Jones to add
compatibles even there are no users of them. The compatibles could be
added - for Arndale Octa and XU3/XU4. I think the only benefit of that
would be attaching the clock driver to the of_node.
