Add support for reading the SERDES statistics of the mv88e8352, using
the standard ethtool -S option. The SERDES interface can be mapped to
either port 4 or 5, so only return statistics on those ports, if the
SERDES interface is in use.
The counters are reset on read, so need to be accumulated. Add a per
port structure to hold the stats counters. The 6352 only has a single
SERDES interface and so only one port will using the newly added
array. However the 6390 family has as many SERDES interfaces as ports,
each with statistics counters. Also, PTP has a number of counters per
port which will also need accumulating.

Refactor the existing code. This helper will be used for SERDES

We're accidentally returning the wrong variable. "cmode" is
uninitialized at this point so it causes a static checker warning.

For implicit namespacing and clarity, prefix the common Port Status
Register macros with MV88E6XXX_PORT_STS and the ones which differ
between implementations with a chosen reference model
(e.g. MV88E6352_PORT_STS_EEE.)
Document the register and prefer ordered hex masks values for all
Marvell 16-bit registers.

The mv88e6xxx.h is meant to contains the chip structures and data.
Rename it to chip.h, as for other source/header pairs of the driver.
At the same time, ensure that relative header inclusions are separated
by a newline and sorted alphabetically.

The mv88e6390X family has 8 SERDES lanes. These can be used for 2
10Gbps ports, ports 9 or 10. If these ports are used at slower speeds,
the SERDES lanes become available for other ports for 1000Base-X.

The mv88e6390 family has a different SERDES implementation. Refactor
the mv88e6352 code into an ops function, so we can later add the
mv88e6390 code.
