Detailed Description

High-precision timer for nrf_802154 on the nRF5340 network core.

Uses TIMER2 at 1 MHz (Contiki-NG rtimer uses TIMER0, the radio uses TIMER1). Only exercised when frame timestamping is enabled; it is currently disabled in the project config, but the timer is provided so the feature can be turned on without further platform work. Channel layout matches Nordic's upstream HP timer contract.
