Subject: [PATCH 1/1] clk: imx6ul: fix clock parent for
 IMX6UL_CLK_ENETx_REF_SEL

Commit 4e197ee880c24ecb63f7fe17449b3653bc64b03c ("clk: imx6ul: add
ethernet refclock mux support") sets the internal clock as default
ethernet clock.

Since IMX6UL_CLK_ENET_REF cannot be parent for IMX6UL_CLK_ENET1_REF_SEL,
the call to clk_set_parent() fails. IMX6UL_CLK_ENET1_REF_125M is the correct
parent and shall be used instead.
Same applies for IMX6UL_CLK_ENET2_REF_SEL, for which IMX6UL_CLK_ENET2_REF_125M
is the correct parent.
