clk: renesas: r8a77995: Add RPC clocks
Describe the various clocks used by the SPI Multi I/O Bus Controller
(RPC-IF) on the R-Car D3 SoC: RPCSRC internal clock, RPC{,D2} clocks
derived from it, and RPC-IF module clock.
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.
