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.

Add device tree nodes for all known controllers.

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.

Use a .dtsi and include it for every device. The nvram partition parameters itself depend on the version of the installed Apple iboot boot loader. m1n1 will fill in the current values provided by Apple's iboot.
