The hardware evolved, so we only need to disable HS400 support on ES1.*
revisions. Update the code.

Another HS400 update for a specific SoC. Builds fine. But I can't test
because of no HW. Reviews from Geert and/or Shimoda-san would be much
appreciated.

LGTM.

arch/arm64/boot/dts/renesas/r8a77980.dtsi always had the
family-specific compatible value, so this is OK.
