This spawned from investigating #6042. I wasn't able to measure any difference as mentioned in the issue, however there were some things worth a change.
Radio teardown never powered the modem down:
deinit()left the modem power domain powered and clocks ungated, and the 802.15.4 driver had no clock teardown at all.

Seems like a speculative change in #5700 which is fixed here.
