ARM: socfpga: dts: Add a clock node for sdmmc CIU 



The CIU(Card Interface Unit) get its clock from the sdmmc_clk_divided clock
which is used to clock the card. The sdmmc_clk_divided clock is the sdmmc_clk
passed through a fixed divider of 4. This patch adds the sdmmc_clk_divided
node and makes the sdmmc_clk it's parent.
