Renesas RZ/Five SoC has almost the same clock structure compared to the
Renesas RZ/G2UL SoC, re-use the r9a07g043-cpg.c file to add support for
RZ/Five SoC.

This patch splits up the clocks and reset arrays for RZ/G2UL and RZ/Five
SoC using #ifdef CONFIG_ARM64 and #ifdef CONFIG_RISCV checks.

i.e. will queue in renesas-clk-for-v5.20.
