dmaengine: idxd: fix dma device lifetime
[ Upstream commit 3978628 ] The devm managed lifetime is incompatible with 'struct device' objects that resides in idxd context. This is one of the series that clean up the idxd driver 'struct device' lifetime. Remove embedding of dma_device and dma_chan in idxd since it's not the only interface that idxd will use. The freeing of the dma_device will be managed by the ->release() function.
