dmaengine: xilinx_dma: fix incompatible param warning in _child_probe() 



In xilinx_dma_child_probe function, the nr_channels variable is
passed to of_property_read_u32() which expects an u32 return value
pointer. Modify the nr_channels variable type from int to u32 to
fix the incompatible parameter coverity warning.

Addresses-Coverity: Event incompatible_param.
