dmaengine: dw-axi-dmac: drop redundant DMAC enable in block start

Browse Source 
axi_chan_block_xfer_start() runs after the controller is already enabled,
so calling axi_dma_enable() again is unnecessary. Remove the redundant
enable call to keep the transfer start path clean and avoid repeated no-op
programming.
