IMX6UL_CLK_ENETx_REF is behind of CLK_ENETx_REF_SEL:
FEC MAC <---------- CLK_ENETx_REF_SEL <--------- CLK_ENETx_REF
\
^------<-> CLK_ENETx_REF_PAD
We should point to the clock selector instead. So, we will be able to
use external clock source from CLK_ENETx_REF_PAD as well.
At same time, remove enet_out clk. It is using always the same clock as
enet_clk_ref and do not help to solve any challenges of this HW.
