Using the RTC1 module for the LK tick (instead of arm systick)
Use the nrf_hal library for peripheral manipulation instead of
direct register access. Fixed race condition in current_time_hires
which would result in non monotonic readings.
Tested with clock_tests on:
nrf52-pca10040-test (nrf52832)
nrf52-pca10056-test (nrf52840)
Using Nordic's nrfx driver for the clock control peripheral since
it address a handful of errata and abstracts some differences
in the nrf52 family of parts.
Almost nothing changes here except moving braces to the same line as the
function declaration. Everything else is largely whitespace changes and
a few dangling files with tab indents.
