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