* ports/nrf: Add micro:bit filesystem. This filesystem has been copied from BBC micro:bit sources [1] and modified to work with the nRF5x port. [1]: https://github.com/bbcmicrobit/micropython/blob/master/source/microbit/filesystem.c * ports/nrf/modules/uos: Make listdir() and ilistdir() consistent. This removes the optional direcotry paramter from ilistdir(). This is not consistent with VFS, but makes more sense when using only the microbit filesystem. Saves about 100 bytes. * ports/nrf/modules/uos: Add code size comment.
