The Retronix R-Car V4H Sparrow Hawk EVTB1 uses 1V8 IO voltage supply
for VDDQ18_25_AVB power rail. Update the AVB0 pinmux to reflect the
change in IO voltage. Since the VDDQ18_25_AVB power rail is shared,
all four AVB0, AVB1, AVB2, TSN0 PFC/GPIO POC[7..4] registers have to
be configured the same way.
Correct the voltage for EVTA1 boards accordingly by patching the U-Boot
control DT in SPL.

NACK. We only allow cherry-picks to dts/upstream. Please use
tools/update-subtree.sh to cherry-pick from devicetree-rebasing git repo.
Do the change in a -u-boot.dtsi companion DTS file if you cannot wait
for the Linux kernel to merge the change.
Cheers,
Quentin
