Interesting. On sm8450 disp_cc_mdss_dptx1_usb_router_link_intf_clk is also sourced from disp_cc_mdss_dptx0_link_div_clk_src (at least judging from the driver file). I'll drop this chunk and update the clock from the sm8650 branch.

Fix seveal odd-looking places in SM8550's dispcc driver: - duplicate entries in disp_cc_parent_map_4 and disp_cc_parent_map_5 - using &disp_cc_mdss_dptx0_link_div_clk_src as a source for disp_cc_mdss_dptx1_usb_router_link_intf_clk The SM8650 driver has been used as a reference.
