dmaengine: xilinx_dma: Add support for residue on direct AXIDMA S2MM
AXIDMA IP supports reporting the amount of bytes transferred on the S2MM
channel in direct mode (i.e. non-SG), but the driver does not. Thus the
driver always reports that all of the buffer was filled.
Add xilinx_dma_get_residue_axidma_direct_s2mm() which gets the residue
amount for direct AXIDMA for S2MM direction.
