====================
mv88e6xxx: Cache scratch config3 of 6352

In mv88e6352 scratch register in Global Control 2 set of registers
returns which port is attached to SERDES. This value is a pin
strapping value and is set after the switch is released from reset.
Thus, it can be cached during chip setup instead of reading the
register everytime when SERDES check is needed.

The series consist of 4 parts:
1. Add new mv88e6352_reset function as ops->reset
2. Cache the register value in this reset function
3. Refactor mv88e6352_g2_scratch_port_has_serdes to use the cached
value.
4. Remove the locks surrounding mv88e6352_g2_scratch_port_has_serdes.
