The RPCSRC clock divider on R-Car D3 is very similar to the one on R-Car
E3, but uses a different pre-divider for the PLL0 parent. Add a new
macro to describe it, reusing the existing clock type for R-Car E3.
As both E3/D3 RPCSRC clock divider are different from the rest of R-Car
Gen3, keep the original implementation from Linux.
Based on Linux commit 40745482eec8 ("clk: renesas: r8a774c0: Add RPC
clocks") by Lad Prabhakar and 9d18f81b3535 ("clk: renesas: r8a77995: Add
RPC clocks") by Geert Uytterhoeven.
