Use newly added R-Car GPIO Gen1 fallback compat string in place of now deprecated non-generation specific R-Car GPIO fallback compat string in DT of r8a7779 SoC. As the driver does not match on "renesas,gpio-r8a7779" there are some run-time considerations for this patch: * When a resulting DTB is used with kernels newer than v4.14 this should not have any run-time effect as renesas,rcar-gen1-gpio is matched by the driver since commit dbd1dad2ab8f ("gpio: rcar: add gen[123] fallback compatibility strings") * However, when used with older kernels GPIO will be disabled as no compat string match will be made by the driver. The regression documented above for the new DTB with old kernel case is acceptable in my opinion.
