arm64: dts: renesas: sparrow-hawk: Set VDDQ18_25_AVB voltage on EVTB1

Browse source

[ Upstream commit 7d1e3aa282 ]

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. As the EVTA1 boards are from a limited run
and generally not available, update the DT to make it compatible with
EVTB1 IO voltage settings.
