ARM: EXYNOS: mark the DMA channel binding for SPI as preliminary

Browse Source 
Bindings for DMA channels are still under discussion and will
change once this has been resolved. Therefore we mark them
the newly added ones as preliminary. Let's hope nobody starts
relying on them...

- interrupts: The interrupt number to the cpu. The interrupt specifier format
depends on the interrupt controller.

official DMA bindings]
- tx-dma-channel: The dma channel specifier for tx operations. The format of
the dma specifier depends on the dma controller.
