Introduce SOC_RENESAS_RZFIVE config option to enable Renesas RZ/Five
(R9A07G043) SoC, along side also add ARCH_RENESAS config option as most
of the Renesas drivers depend on this config option.

And instead you would redefine ARCH_RENESAS in this file and not use SOC_RENESAS* at all? Will save me having to purge the the SOC symbol when I do the conversion.

Hi Conor,
Thank you for the review.

Yes we do need SOC_BUS due to soc_device_register() call in [0].
Digging further I realized we can drop the above SOC_BUS as
SOC_RENESAS is selecting SOC_BUS [1]
[0] https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/drivers/soc/renesas/renesas-soc.c?h=v6.0-rc5#n487

I was under the impression we didn't come to a conclusion so kept the
patch as is. I'll just make ARCH_RENESAS visible as Geert suggested
something like below:
config ARCH_RENESAS
bool "Renesas RISC-V SoCs"
select GPIOLIB
select PINCTRL
select RESET_CONTROLLER
