ENGR00169906-3 MXS-DMA : add new flags
We catch a DMA timeout bug in the NAND in mx6q.
If we do not set the WAIT4END in the middle DMA command structure
of the long DMA command chain, a DMA timeout may occurs.
In order to fix the bug, we should let the driver to
set the proper DMA flags in the DMA command structrues.
So add the new flags for MXS-DMA.
The driver can use these flags to control the DMA in a flexible way.
