eeprom: at24: refactor at24_probe()
The code in at24_probe() is pretty mangled. It can be cleaned up a bit by doing things one by one. Let's group the code by logic: parse and verify pdata, initialize the regmap, allocate and fill the fields of at24_data, allocate dummy i2c devices, initialize pm & register with nvmem.
