Thanks for your patch!

Given RZ/V2L is RZ/G2L + DRP-AI, and the common clock IDs are the
same, what about reusing r9a07g044-cpg.c, and just adding a separate
r9a07g054_cpg_info?
When you add DRP-AI clocks and resets later, you just have to make
sure .num_{core_clks,mod_clks,resets} are correct, similar to how
drivers/pinctrl/renesas/pfc-r8a77951.c handles common and automotive
pin groups and functions.
