The init_data and of_node fields of the axp2xx_matches tables are filled
at each device probe by the axp20x_regulator_parse_dt function (which then
calls the of_regulator_match function).
This means we can probe a new device and consider data initialized during
the probe of another device as valid.
Reset init_data and of_node field to NULL before each probe in order to
avoid this kind of issue.
