soc: renesas: Kconfig: Explicitly select GPIOLIB and PINCTRL config under SOC_RENESAS

GPIOLIB and PINCTRL config options are required by all ARM32/ARM64/RISC-V
Renesas SoCs, so instead of selecting them under ARCH_RENESAS for each
architecture just explicitly select them under SOC_RENESAS config option
which will be visible for all the three architectures (if ARCH_RENESAS is
enabled).
