Subject: [PATCH] spi: spi-imx: use correct enumeration type

The fourth argument of dmaengine_prep_slave_sg needs to be of the
enumeration type dma_transfer_direction instead of dma_data_direction.
Since the used enumeration values actually stay the same, this is not
an actual issue at runtime.

This showed up when I tried using LLVM/clang to build a kernel for
a Freescale Vybrid based board.
