thermal/drivers/rcar_gen3_thermal: 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.
