arm64: dts: renesas: r8a779f0: Add GPIO nodes

Add device nodes for the General Purpose Input/Output (GPIO) blocks on
the Renesas R-Car S4-8 (R8A779F0) SoC.

Disable gpio4-7, as they do not seem to be accessible as-is using either
the Control Domain (0xffd9....) or Application Domain (0xdfd9....)
addresses.

How to make the Control Domain release the bus guard, so the registers
become accessible?
