gpio: renesas: Wrap quirks in struct rcar_gpio_data

Wrap the RCAR_GPIO_HAS_INEN quirk in more flexible struct rcar_gpio_data {}
in preparation for addition of Renesas R-Car Gen5 GPIO controller support.
The Renesas R-Car Gen5 GPIO controller requires more than a single quirk
to properly describe it, therefore increase the flexibility and introduce
full match data structure, and use it throughout the driver. No functional
change.
