dmaengine: imx-dma: Disable use of hw_chain to fix sg_dma transfers.

HW chaining is currently broken in imx-dma. It can be easily reproduced doing
intensive accesses to a external MMC card and checking how the file system
is corrupted.

Preventing the driver to use HW chaining solves these issues.
