MYNEWT-313: Low power modifications
There were a number of changes with this commit:
1) Porting the nrf51 code which uses an RTC timer for the OS timer tick to
the nrf52. The nrf52 used to use a higher power timer for its os tick.
2) Changing OS_TICKS_PER_SEC on the nrf51 and nrf52 to 128 (from 1000).
3) Modified blinky as it was doing a os_time_delay(1000) instead of
os_time_delay(OS_TICKS_PER_SEC).
> Add Low Power Support and tie-it into drivers that are linked together in a

>
> Need to have drivers support turning on and off based on system power
> settings automatically.Also need someway to semantically look-up initialized
> drivers in the system.
> For this, a device tree is proposed, where drivers register with the system,
> and provide a device ID. This device ID is what the rest of the system uses
> to look up a specific device.
> The OS uses this device list to notify when the system goes into a low power
> state, and the various drivers handle putting the system into a low power
> state.
