Subject: [PATCH] dmaengine/dw_dmac: Divide one sg to many desc, if sg len is
 greater than DWC_MAX_COUNT

If len passed in sg for slave_sg transfers is greater than DWC_MAX_COUNT, then
driver programmes controller incorrectly.  This patch adds code to handle this
situation by allocation more than one desc for same sg.
