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