Andrew Lunn a61e540634 net: dsa: mv88e6xxx: Release mutex between each ATU read
The PTP code needs low latency access to the PTP hardware timestamps.
Reading all the ATU entries in one go adds a lot of latency to the PTP
code. So take and release the reg_lock mutex for each individual MAC
address in the ATU, allowing the PTP thread jump in between.
