nrf/modules/nrf: Add function to enable/disable DCDC.

Browse Source 
This function can be used to enable and disable the DC/DC converter with or
without the Bluetooth stack enabled.  It can also be used to query the
current state of the DC/DC.

This commit also adds a definition of ARRAY_SIZE needed by nrfx HAL-layer.
