flash Kinetis: split kinetis_chip from kinetis_flash_bank

Kinetis flash driver probed and decoded chip repeatedly for each flash
bank. Bank ordering used global bank number so multi-target
configuration was broken.

The change introduces kinetis_probe_chip() which reads SIM SDID
and SIM FCFG registers, decodes Kinetis series and family
and fills struct kinetis_chip. This probe runs once for all banks.

struct kinetis_chip contains pointers to all flash banks embeded
in the MCU. It simplifies iteration over all or specific MCU banks.

kinetis_probe_chip() generates MCU name and some informational messages
are improved.
