From: Philippe Schenker <[email protected]>
This commit introduces support for the 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.

KSZ8567 switch is similar to KSZ9897/KSZ9567 except that internal phys
are without gigabit capability.
So add KSZ8567 related updates adjacent to KSZ9567. So it will be
grouped together and easier to update in case new features are added to
this switch family.
Hi Arun and thanks for your message!

I actually tried sorting it kind of alphanumerically but I can put it
next to KSZ9567, will do in a v2 but wait a bit more for some feedback
to arrive.
