MYNEWT-714: Add DC/DC enable for nordic platforms
As discussed on the dev list, added a call to hal_system_init() in
the startup code (in gcc_startup_nrfxx.s). Added the function
hal_system_init() to hal_system.c for both nrf51 and nrf52. All
BSP directories were updated to enable DC/DC regulator EXCEPT for
arduino 101 and BBC microbit. I cannot find specific microbit
schematics but the reference design does not appear to have the
necessary circuitry. Not sure about Arduino 101.

> The current controller code enables the LDO regulator and has no option to
> enable the DC/DC regulator. This option should be added to the bsp for nordic
> platforms as it saves a considerable amount of power.
