Right now mach-imx6ul registers a fixup for the ksz8081 phy. The same register values can be set through the micrel phy driver by using dts properties.
This seems preferable and allows cleanly fixing suspend/resume.

This patch only fixes suspend on 6ul evk in combination with 79e498a9c7da ("net: phy: micrel: Restore led_mode and clk_sel on resume"). It is otherwise not very useful to backport just the DT patch.
That patch was earlier backported but then reverted from 4.9 because it unexpectedly caused issues when combined with other phy patches applied out-of-order. It seems a correct fix was eventually made (by backporting bfe72442578b) and 79e498a9c7da could now be restored:

I'm not sure fixing nfsroot suspend/resume on dev boards meets the criteria for linux-stable, especially since it already caused trouble once. In general I'd class "fixing things that never worked before" as not particularly suitable for backporting.
