[PATCH v5 01/11] spi: imx: terminate RX DMA transaction in case of TX DMA timeout

[Anton Bondarenko <anton.bondarenko.sama@gmail.com>]

Not only TX DMA should be terminated, but RX DMA also. It's required
to avoid accidential DMA memory writes from RX DMA channel and properly
terminate transaction.
