mxs platform has been converted to device tree.
There is no need to check if np is NULL after doing:
np = of_find_compatible_node(NULL, NULL, "fsl,imx[23/28]-clkctrl");
,as it will always be non-NULL.

Hmm, technically the check is still valid, as np can be NULL if
the clkctrl node with correct compatible string is not present.
