No description provided.

Both the nrf_802154_clock_hfclk_start() and
nrf_802154_clock_hfclk_stop() can potentially be called form ZLI and
non-ZLI contexts and consecutive calls are not guaranteed to be
alternating.

Added an implementation that uses the EGU to de-escalate to a non-ZLI
context from which it is safe to use the Zephyr API that
enables/disables the HFXO.
