bm: Exposed cortexm-functions to be used for nRF-targets. 

Exposed cortexm_reset & cortexm_halt_request in order to be populated as
operators for nRF-targets. Also added the already exposed cortexm_halt_resume
functon to nRF. By this it will be possible to handle such blackmagic probe
commands towards connected nRF-targets.
