clk: imx: imx7d: Fix parent clock for OCRAM_CLK

Browse Source 
The parent of OCRAM_CLK should be axi_main_root_clk
and not axi_post_div.

before:

    axi_src                     1       1       332307692       0 0
      axi_cg                    1       1       332307692       0 0
        axi_pre_div             1       1       332307692       0 0
          axi_post_div          1       1       332307692       0 0
            ocram_clk           0       0       332307692       0 0
            main_axi_root_clk   1       1       332307692       0 0

after:

    axi_src                     1       1       332307692       0 0
      axi_cg                    1       1       332307692       0 0
        axi_pre_div             1       1       332307692       0 0
          axi_post_div          1       1       332307692       0 0
            main_axi_root_clk   1       1       332307692       0 0
              ocram_clk         0       0       332307692       0 0
