targets: add target circuitplay-bluefruit Add a target for the Adafruit Circuit Playground Bluefruit, which is based on the nRF52840. Adds the necessary code for the machine package and the json and linker script files in the targets directory. The machine package code is based on board_circuitplay_express.go, with modifications made by consulting the wiring diagram on the adafruit website here: https://learn.adafruit.com/adafruit-circuit-playground-bluefruit/downloads Also adds support to the uf2 conversion packacge to set the familyID field. The Circuit Playground Bluefruit firmware rejects uf2 files without the family id set to 0xADA52840 (and without the flag specifying that the family id is present).

nrf: add SoftDevice support for the Circuit Playground Bluefruit This also fixes a bug: the Bluefruit doesn't have a low frequency crystal. Somehow non-SoftDevice code still worked. However, the SoftDevice won't initialize when this flag is set incorrectly.
