pinctrl: renesas: Remove R-Car H3 ES1.* handling

R-Car H3 ES1.* was only available to an internal development group and
needed a lot of quirks and workarounds.  These become a maintenance
burden now, so our development group decided to remove upstream support
and disable booting for this SoC.  Public users only have ES2 onwards.
