flash Kinetis: Add support for newer KW series

Add support for flashing newer members of the NXP Kinetis KW family

Supported devices:
 - KW20Z
 - KW30Z
 - KW40Z
 - KW21Z
 - KW31Z
 - KW41Z

The earlier KW2xD and KW01Z devices are already supported by the code
for the older K-series.

Verified working on the FRDM-KW41Z development board.
Tested flashing both via GDB `load` and directly via OpenOCD flash
write commands.
