clk: qcom: dispcc-glymur: Fix DSI byte clock rate setting

The clock tree for byte_clk_src is as follows:

   ┌──────byte0_clk_src─────┐
   │                        │
byte0_clk            byte0_div_clk_src
                            │
                     byte0_intf_clk

If both of its direct children have CLK_SET_RATE_PARENT with different
requests, byte0_clk_src (and its parent) will be reconfigured. In this
case, byte0_intf should strictly follow the rate of byte0_clk (with
some adjustments based on PHY mode).

Remove CLK_SET_RATE_PARENT from byte0_div_clk_src to avoid this issue.
