Add device tree nodes for all known controllers. The missing ones could be guessed and tested with a little effort but since the devices expose no pins and no new devices are expected there is no point in spending the effort. SPI is used for spi-nor and input devices like keyboard, trackpad, touchscreen and fingerprint reader. Only the spi-nor flash has upstream drivers. Support for it will be added in a following commit.
