drivers: timer: nrf_rtc_timer: Change type of channel argument

Browse source 
There was an inconsistency in the API as z_nrf_rtc_timer_chan_alloc
returned int but other function were using uint32_t for channel
argument. Updated api to use int32_t everywhere.

Update nrf_802154 driver which was using this api to use int32_t.
