m_can can be a wakeup source on some devices. Especially on some of the
am62* SoCs pins, connected to m_can in the mcu, can be used to wakeup
the SoC.

The wakeup-source property defines on which devices m_can can be used
for wakeup and in which power states.

The pins associated with m_can have to have a special configuration to
be able to wakeup the SoC. This configuration is described in the wakeup
pinctrl state while the default state describes the default
configuration.

Thanks, the bot also notified me about this issue. I wasn't able to
solve it without updating the dt-schema, so I submitted a pull request
there:
