The 'wakeup-source' property is declared as a phandle-array in both YAML
bindings and Device Tree source files. However, the driver currently
uses of_property_read_bool() to check for its existence.

According to the function's documentation, usage on non-boolean property
types is deprecated. Switch to of_property_present() to comply with the
recommended API for checking the presence of a property.

Fixes: 04d5826b074e ("can: m_can: Map WoL to device_set_wakeup_enable")
