Have you enabled the drivers in sdk_config.h?

Inside nrf_drv_clock.c for example, there is a macro "guard":

#if NRF_MODULE_ENABLED(CLOCK)
...
driver code
...
#endif

To enable the driver you need to define:

#define CLOCK_ENABLED 1

inside sdk_config.h. You can read more about who to use the sdk_config.h file here: nRF5 SDK v14.2.0: SDK configuration header file
