The CAN transceiver on some boards has an STB pin which is used to control its standby mode. Add an optional property stb-gpios to toggle the same.

The m_can.txt is for the m_can framework. If this is specific to the platform then it really does not belong here. If the platform has specific nodes then maybe we need a m_can_platform.txt binding for specific platform nodes. But I leave that decision to Rob. Also I prefer you spell out standby like the gpios are spelled out in the tcan binding. Dan
