cmd: eeprom: Refactor eeprom device specifier parsing

In preparation for allowing to access eeprom by driver-model device
name, refactor the eeprom device specifier parsing. Instead of filling
two parameters (i2c_bus, i2c_addr), the parsing function now fills one
parameter of type struct eeprom_dev_spec.
