arm64: dts: apple: t8112: Add spi controller nodes

Browse source

Apple silicon devices have one or more SPI devices. 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.
