regulator: s2mps11: Fix NULL pointer of_node value when using platform data

Browse Source 
When platform_data is used for regulator (of_node of sec-core MFD device
is NULL) the config.of_node for regulator is not initialized. This NULL
value of config.of_node is later stored during regulator_register().
Thus any call by regulator consumers to of_get_regulator() will fail on
of_parse_phandle() returning NULL.

In this case (using platform_data and parent's driver of_node is NULL)
set the config.of_node to reg_node from platform_data.
