lpc32xx_xmit_dma() starts a DMA transfer and waits up to one second

after unmapping the buffer.

A timed out read can therefore return success with incomplete data, and
a timed out write can continue the NAND operation without proof that the
DMA payload reached the controller.

Applied to mtd/fixes, thanks!

Patche(s) should be available on mtd/linux.git and will be
part of the next PR (provided that no robot complains by then).

Kind regards,
