clk: renesas: rzv2h: Fix missing CLK_SET_RATE_PARENT flag for ddiv clocks

Commit bc4d25fdfadf ("clk: renesas: rzv2h: Add support for dynamic
switching divider clocks") missed setting the `CLK_SET_RATE_PARENT`
flag when registering ddiv clocks.

Without this flag, rate changes to the divider clock do not propagate
to its parent, potentially resulting in incorrect clock configurations.

Fix this by setting `CLK_SET_RATE_PARENT` in the clock init data.
