dmaengine: xilinx: dpdma: remove comparison of unsigned expression

Browse Source 
xilinx_dpdma_config() channel id is unsigned int and compares with
ZYNQMP_DPDMA_VIDEO0 which is zero, so remove this comparison

drivers/dma/xilinx/xilinx_dpdma.c:1073:15: warning: comparison of
unsigned expression in ‘>= 0’ is always true [-Wtype-limits] if
	(chan->id >= ZYNQMP_DPDMA_VIDEO0 && chan->id <= ZYNQMP_DPDMA_VIDEO2)
