[PATCH v4 2/9] dt-bindings: can: m_can: Add vio-supply

[Markus Schneider-Pargmann]

The m_can unit can be integrated in different ways. 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 example 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.
