Drop these leading spaces.

For such imx6sl dts changes, please put a prefix 'ARM: dts: imx6sl: ...'
on the patch subject.

Please see my reply to your previous patch.

The lines are somehow too long.  The following one might be easier to
read.

			clocks = <&clks IMX6SL_CLK_ARM>,
				 <&clks IMX6SL_CLK_PLL2_PFD2>,
				 <&clks IMX6SL_CLK_STEP>,
				 <&clks IMX6SL_CLK_PLL1_SW>,
				 <&clks IMX6SL_CLK_PLL1_SYS>;
