Add device nodes for the General Purpose Input/Output (GPIO) block on
the Renesas R-Car V3u (r8a779a0) SoC.

As there is no node for the PFC yet, all "gpio-ranges" properties are
commented out.

This needs verification on real hardware, as the hardware manual is
unclear w.r.t. the following points:
  - Module clocks and interrupt mappings,
  - There are more/multiple resets for the PFC[0-3] in the Software
    Reset/Reset Clearing Registers 12, 13, and 14.
    The BSP picked up a different set.
