That is not correct: the driver does not match against "renesas,gpio-r8a7779".
Hence this breaks using a new DTS and an old kernel (which we may decide not
to care about for R-Car Gen1, though).
But at least the DTS change should be postponed until commit d10bbd156926e65d
("gpio: rcar: add gen[123] fallback compatibility strings") has hit mainline.
