[PATCH v2 1/9] spi: spi-s3c64xx: swap s3c64xx_spi_set_cs() and s3c64xx_enable_datapath()

[Łukasz Stelmach]

This and the next patch fix issues with DMA transfers bigger than
512 bytes on Exynos3250. Without the patches such transfers fail
to complete. This solution to the problem is found in the vendor kernel
for ARTIK5 boards based on Exynos3250.
