clk: renesas: r9a09g077: Propagate rate changes to parent clocks
Add the CLK_SET_RATE_PARENT flag to divider clock registration so that rate
changes can propagate to parent clocks when needed. This allows the CPG
divider clocks to request rate adjustments from their parent, ensuring
correct frequency scaling and improved flexibility in clock rate selection.
