This module implements a kernel device driver for the nRF Global Real

drivers, rather than leaving it up to SYS_INIT.

Start the SYSCOUNTER when initializing the GRTC. This should only be

handled by one processor in the system.

Compile additional driver code for enabling management functionality of

the GRTC. Usually this is only needed by the processor that is starting

the SYSCOUNTER, but can be shared by multiple processors in the system.

The value (in us) ensures that the wakeup event will not fire
|
|
too early. In other words, applying SYSCOUNTER sleep state for less than
|
|
NRF_GRTC_SYSCOUNTER_SLEEP_MINIMUM_LATENCY period makes no sense.

This feature prevents the SYSCOUNTER from sleeping when any core is in
