clk: renesas: rcar-gen3: Allow changing the RPC[D2] clocks 

[ Upstream commit 0d67c0340a ]

I was unable to get clk_set_rate() setting a lower RPC-IF clock frequency
and that issue boiled down to me not passing CLK_SET_RATE_PARENT flag to
clk_register_composite() when registering the RPC[D2] clocks...
