[ Upstream commit 145dfd70b9c70e5bc03494a7ce8fa3748ac01af3 ]
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.
