This breaks iMX7d.

One can't see enough context in the patch above, but in linux-next this
section is under
case IMX7D:
case IMX8MQ:
It's being applied to imx7d and not just imx8mq and so breaks because
imx7d dts files don't have this clock. Not sure if this is a bug in
this commit or some kind of merge/rebase mistake.
