targets: add FRDM-RW612

Easiest method to test WiFi APIs is to use a board where WiFi is already supported :)
Comes with its own set of issues:
* pyocd is not supported, use JLink to flash instead
* The .dfu.bin file should be flashed at 0x18323000
* Debug UART (printk) on JLink port, Serial on native USB
