[PATCH AUTOSEL 4.14 71/73] dmaengine: dma-jz4780: Return error if not probed from DT

From: Paul Cercueil [ Upstream commit 54f919a04cf221bc1601d1193682d4379dacacbd ] The driver calls clk_get() with the clock name set to NULL, which means that the driver could only work when probed from devicetree. From now on, we explicitly require the driver to be probed from devicetree.
