After the "dts: ksz8974: add support for ksz8863"
(SHA1: b0e4886dfa) commit the port numbering
for KSZ8794 was wrong.
This IC has 3 ETH ports (with linear offset), with port 4 being the
"master" with non linear offset (i.e. 0x50 instead of linear 0x40).
Such situation can be explained with similarity of this IC to ksz8795,
which has 4 LAN ports, and then the 0x40 offset is used.

Changed slave interface initialization code to be more generic and less
dependent on a specific number of ports.

Changed port numbers to start at zero since they're used as indexes
into various arrays in the code.

This patch adds support for Microchip's KSZ8794 DSA device, which for
switch and PHY control uses SPI communication.
This driver also provides support for handling tail tagging added and
decoded in the KSZ8794 device as well as modifying entries in the
static MAC address table.
It is also possible to use GPIO pin to reset KSZ8794 switch.
When the "reset-gpios" property is not defined, software based reset
is performed instead.
The KSZ8794 can now be used on boards which have SPI CS only available
as GPIO pin.
