net: dsa: mv88e6xxx: remove unused 88E6165 register definitions

Browse Source 
Remove the unused 88E6165 register definitions. For the port
registers, add a comment describing that each arrival and departure
offset is for a set of four registers that correspond with status,
two timestamp registers and the PTP sequence ID captured from the
packet.
