mcu/nrf52: Handle APROTECT
Newest hardware revisions of NRF52840, NRF52810 (and others) now have
access port protection enabled by default.
To enable debugger use after reset nrf52_handle_approtect() should be
called during startup.
SystemInit from NRF SDK now has and uses code to handle APROTECT, this
change do the same for mynewt.
