ENGR00169906-5 GPMI : change the code for new interface

If we do not set the WAIT4END in the middle DMA command structure
of the long DMA command chain, a DMA timeout may occurs.

The reason of the DMA timeout is:
	[1] We do not set the WAIT4END in the DMA command structure
	    which do the ECC READ PAGE by the BCH.
	[2] So the following DMA command structure (maybe in other DMA
		CHAIN)may disable the BCH module.
	[3] If the time delay between [2] and [1] is long enough,
	    it's ok. But if the time delay is not long enough, the BCH
	    module may become unnormal, so it can not finish its job.
	    The DMA will timeout in this case.

We have changed the DMA interface to fix the bug, now use the new
interface.
