From: Takeshi Kihara <takeshi.kihara.df@...>

The R-Car GPIO driver cannot be enabled when Renesas SoC's ARCH configs
(ARCH_RENESAS, ARCH_R8A7795, ARCH_R8A7796 and ARCH_R8A77965) are enabled
only.

As GPIOs are a critical resource for proper operation on Renesas
platforms, this patch selects GPIOLIB, just like is done for other SoC
vendors, and on Renesas arm32 SoCs.
