Subject: [PATCH 11/11] usb: gadget: udc: renesas_usb3: 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.

Please apply individually per subsystem. There are no dependencies and the SoC
doesn't boot anymore since v6.3-rc1.
