f5f6959444 gpio: rmobile: Add Renesas RCar GPIO driver 
Add GPIO driver for the Renesas RCar SoCs . The driver currently supports
only the RCar Gen3 R8A7795 and R8A7796 SoCs, but is easily extensible for
the other RCar SoCs as well.

This driver is meant to replace the pinmux part of SH_GPIO_PFC driver.
