clk: renesas: rcar-gen3: Disable R-Car H3 ES1.*

Browse source

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
for this SoC. Public users only have ES2 onwards.

In addition to the ES1 specific removals, a check for it was added
preventing the machine to boot further. It may otherwise inherit wrong
clock settings from ES2 which could damage the hardware.
