The Exynos4 SPI controller uses the PL330 DMA controller which has
migrated to the generic DMA bindings since commit b5be04d35dbb2e00
"spi: s3c64xx: Modify SPI driver to use generic DMA DT support".
Use the generic bindings to specify the corresponding DMA to make
the SPI usable again on Exynos4x12 SOCs.
