net: add support for KSZ9477/KSZ9897/KSZ9567 GbE switch
The Microchip KSZ9477/KSZ9897/KSZ9567 7-Port Gigabit Ethernet Switches
support SGMII/RGMII/MII/RMII with register access via SPI, I2C, or MDIO.
This driver currently supports I2C register access but SPI or MDIO register
access can be easily added at a later time.
Tagging is not implemented and instead the active port is tracked to
avoid needing a tag to store port information.
This was tested with the imx8mm-venice-gw7901 board which has a
KSZ9897S switch with an IMX8MM FEC MAC master connected via RGMII_ID.
