Prepend "ti,am62-mcan" to the m_can device compatible property since this compatible adds out-of-band wakeup functionality. The m_can pins can be a wakeup source in the deepest low power states, despite being in power domains which are OFF during deeper low power states since it has the out-of-band wakeup capability.
