Andrew Boie 42cfd4ff26 kernel: expose k_busy_wait() to user mode
If we just had the kernel's implementation, we could
just move this to lib/, but possible arch-specific
implementations dictate that we just make this a
syscall.

Alberto Escolar Piedras ceaa46d07b new simulated board: nrf52_bsim
Added a new simulated board, which models the NRF52832 SOC.

Its main use is for workstation testing and simulation of
the BLE stack and any application which relies mostly on it.

It uses BabbleSim (http://Babblesim.github.io) for the radio
simulation.
And the NRF52 HW models hosted in that same GitHub organization:
https://github.com/BabbleSim/ext_NRF52_hw_models

For speed it uses the POSIX arch to (not) emulate the CPU.
It uses Vanilla Zephyr, with a couple of configuration differences:
* It uses (like other POSIX arch boards) the system libC
* It does not use the nrfx hosted by Zehpyr in ext/, but the one
  provided by the HW models.
Otherwise it relies in the same drivers as the real NRF52 boards.
