Theoretically you don't need anything to make it work - nodes being a
children of a I2C master will instantiate i2c_clients, offspring of a
SPI master will become spi_devices. Then you register two drivers - I2C
and SPI ones, probably sharing most of the code - both matching the same
compatible value. The I2C one will be bound only with the I2C nodes, the
same applies to SPI.
I hope :-)
