sfc: Stop/re-start PTP when stopping/starting the datapath.
[ Upstream commit 2ea4dc28a5bcec408e01a8772763871638a5ec79 ]
This disables PTP when we bring the interface down to avoid getting
unmatched RX timestamp events, and tries to re-enable it when bringing
the interface up.
[bwh: Make efx_ptp_stop() safe on Falcon. Introduce
efx_ptp_{start,stop}_datapath() functions; we'll expand them later.]
Fixes: 7c236c43b838 ('sfc: Add support for IEEE-1588 PTP')
