dma: dw-axi-dmac: remove unnecessary axi_dma_enable() calling

From: Niravkumar L Rabara <[email protected]>

DMA is always enabled before calling axi_chan_block_xfer_start(), so it does not need to be enabled again here.

Re-enabling DMA causes random failures in the dmatest test when running multiple iterations.
e.g.

[   29.600722] dmatest: dma0chan2-copy0: summary 100 tests, 1 failures 160.26 iops 1299 KB/s (0)
