arm64: dts: apple: t600x: Add spi controller nodes

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.
