clk: renesas: r9a07g043: Add support for RZ/Five SoC

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.
