Fix the mipi dphy root divider to mipi_dphy_pre_div, this would remove a orphan
clock and set the correct parent.

before:
cat clk_orphan_summary
enable prepare protect
clock count count count rate accuracy phase
----------------------------------------------------------------------------------------
mipi_dphy_post_div 1 1 0 0 0 0
mipi_dphy_root_clk 1 1 0 0 0 0

cat clk_dump | grep mipi_dphy
mipi_dphy_post_div 1 1 0 0 0 0
mipi_dphy_root_clk 1 1 0 0 0 0

after:
cat clk_dump | grep mipi_dphy
mipi_dphy_src 1 1 0 24000000 0 0
mipi_dphy_cg 1 1 0 24000000 0 0
mipi_dphy_pre_div 1 1 0 24000000 0 0
mipi_dphy_post_div 1 1 0 24000000 0 0
mipi_dphy_root_clk 1 1 0 24000000 0 0
