The device tree node is an SPI device so it must reside inside a SPI bus
device tree node, see spi/spi-bus.txt
This switch could have two different management interface.
If SPI interface is used, the device tree node is an SPI device so it must
reside inside a SPI bus device tree node, see spi/spi-bus.txt
When the chip is connected to a parallel memory bus and work in memory-mapped
I/O mode, a platform device is used to represent the vsc73xx. In this case it
must reside inside a platform bus device tree node.
