dmaengine: at_hdmac: check return value of of_find_device_by_node() in at_dma_xlate()
[ Upstream commit 0cef8e2c5a07d482ec907249dbd6687e8697677f ]
The reurn value of of_find_device_by_node() is not checked, thus null
pointer dereference will be triggered if of_find_device_by_node()
failed.
Fixes: bbe89c8e3d59 ("at_hdmac: move to generic DMA binding")
