Some USI blocks can be configured as SPI controllers. Add corresponding SPI nodes to Exynos850 SoC device tree.

For the future: please keep properties sorted by name, so clocks+name, dmas+name, interrupts, pinctrl+name, more-or-less matching DTS coding style. address/size cells can go to the end. Best regards, Krzysztof
