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.
