For AM62 the unit is integrated in different parts of the system (MCU or Main domain) and can be powered by different external power sources. For examle on am62-lp-sk mcu_mcan0 and mcu_mcan1 are powered through VDDSHV_CANUART by an external regulator. To be able to describe these relationships, add a vio-supply property to this binding.
