If you want to change psy_cfg, you need to pass it by reference
and not by value (i.e. use &psy_cfg here and a pointer as argument
of bq256xx_parse_dt). Providing psy_cfg like this creates a copy
of the struct.

Did you runtime test this version? It should crash when accessing
the properties because of psy_cfg.drv_data being NULL.

Here it's also better to just provide the address of psy_cfg
(but not strictly necessary).
