dma: Add support to program MIC x100 status descriptiors
The MIC X100 DMA engine has a special status descriptor which writes an 8 byte value to a destination location. This is used to signal completion of all DMA descriptors prior to the status descriptor. This patch add a new DMA engine API which enables updating a destination address with an 8 byte immediate data value.
