zynq_fpga: use sgtable-based scatterlist wrappers
Use common wrappers operating directly on the struct sg_table objects to
fix incorrect use of statterlists related calls. dma_unmap_sg() function
has to be called with the number of elements originally passed to the
dma_map_sg() function, not the one returned in sgtable's nents.
