[PATCH] misc: scu: Remove child dev bind

Remove the child device binding codes for clk and iomux nodes, because
the misc uclass has added such operation in post-bind. If we keep the
codes in scu bind, child devices will be created twices. Find the
problem by "dm uclass" command.

uclass 24: clk
0   * clk @ fce22380, seq 0, (req -1)
1     clk @ fce23110

uclass 67: pinctrl
0   * iomuxc @ fce22470, seq 0, (req -1)
1     iomuxc @ fce231c0

After the fix:

uclass 24: clk
0   * clk @ fce22380, seq 0, (req -1)

uclass 67: pinctrl
0   * iomuxc @ fce22470, seq 0, (req -1)
