Add support for the KSZ9563 3-Port Gigabit Ethernet Switch to the
ksz9477 driver. The KSZ9563 supports both SPI (already in) and I2C. The
ksz9563 is already in the device tree binding documentation.

The KSZ9893 3-Port Gigabit Ethernet Switch can be controlled via SPI,
I²C or MDIO (very limited and not supported by this driver). While there
is already a compatible entry for the SPI bus, it was missing for I²C.

Several cases of overlapping changes which were for the most
part trivially resolvable.

The KSZ driver uses one regmap per register width (8/16/32), each with
it's own lock, but accessing the same set of registers. In theory, it
is possible to create a race condition between these regmaps, although
the underlying bus (SPI or I2C) locking should assure nothing bad will
really happen and the accesses would be correct.
To make the driver do the right thing, add one single shared mutex for
all the regmaps used by the driver instead. This assures that even if
some future hardware is on a bus which does not serialize the accesses
the same way SPI or I2C does, nothing bad will happen.
Note that the status_mutex was unused and only initied, hence it was
renamed and repurposed as the regmap mutex.

Add support for the KSZ9567 7-Port Gigabit Ethernet Switch to the
ksz9477 driver. The KSZ9567 supports both SPI and I2C. Oddly the
ksz9567 is already in the device tree binding documentation.

Add KSZ9477 I2C driver support. The code ksz9477.c and ksz_common.c are
used together to generate the I2C driver.
