flash Kinetis: Add support for newer KW series

Joakim Nohlgård · FreddieChopin · commit 2c8602ed9f08 · 2017-06-17T12:02:31.000+01:00
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.
