flash Kinetis: fix probe for FlexNVM partitioned as EEPROM backup
If a MCU has FlexNVM partitioned as EEPROM backup only
(no data flash), kinetis_probe_chip() detects zero fcfg2_maxaddr1
and adjusts flash banks count to 1, what is obviously wrong.
The change limits the test to devices without FlexNVM.
Also missing case 0x07 is added to switch (fcfg1_depart)
