KSZ8895/KSZ8864 is a switch family developed before KSZ8795 and after
KSZ8863, so it shares some registers and functions in those switches.
KSZ8895 has 5 ports and so is more similar to KSZ8795.
KSZ8864 is a 4-port version of KSZ8895. The first port is removed
while port 5 remains as a host port.

This commit adds the dt-binding for KSZ8567, a robust 7-port
Ethernet switch. The KSZ8567 features two RGMII/MII/RMII interfaces,
each capable of gigabit speeds, complemented by five 10/100 Mbps
MAC/PHYs.
This binding is necessary to set specific capabilities for this switch
chip that are necessary due to the ksz dsa driver only accepting
specific chip ids.
The KSZ8567 is very similar to KSZ9567 however only containing 100 Mbps
phys on its downstream ports.

SPI and I2C bus node names are expected to be "spi" or "i2c",
respectively, with nothing else, a unit-address, or a '-N' index. A
pattern of 'spi0' or 'i2c0' or similar has crept in. Fix all these
cases. Mostly scripted with the following commands:
git grep -l '\si2c[0-9] {' Documentation/devicetree/ | xargs sed -i -e 's/i2c[0-9] {/i2c {/'
git grep -l '\sspi[0-9] {' Documentation/devicetree/ | xargs sed -i -e 's/spi[0-9] {/spi {/'
With this, a few errors in examples were exposed and fixed.

DSA switches can fall into one of two categories: switches where all ports
follow standard '(ethernet-)?port' properties, and switches that have
additional properties for the ports.
The scenario where DSA ports are all standardized can be handled by
switches with a reference to the new 'dsa.yaml#/$defs/ethernet-ports'.
The scenario where DSA ports require additional properties can reference
'$dsa.yaml#' directly. This will allow switches to reference these standard
definitions of the DSA switch, but add additional properties under the port
nodes.

The ksz_switch_chips[] element for KSZ9477 says that port 5 is an xMII
port and it supports speeds of 10/100/1000. The device tree example does
declare a fixed-link at 1000, and RGMII is the only one of those modes
that supports this speed, so use this phy-mode.
The microchip,ksz8565 compatible string is not supported by the
microchip driver, however on Microchip's product page it says that there
are 5 ports, 4 of which have internal PHYs and the 5th is an
MII/RMII/RGMII port. It's a bit strange that this is port@6, but it is
probably just the way it is. Select an RGMII phy-mode for this one as
well.
