dmaengine: at_hdmac: fix device leak on of_dma_xlate()
commit b9074b2d7a230b6e28caa23165e9d8bc0677d333 upstream.
Make sure to drop the reference taken when looking up the DMA platform
device during of_dma_xlate() when releasing channel resources.
Note that commit 3832b78b3ec2 ("dmaengine: at_hdmac: add missing
put_device() call in at_dma_xlate()") fixed the leak in a couple of
error paths but the reference is still leaking on successful allocation.
Fixes: bbe89c8e3d59 ("at_hdmac: move to generic DMA binding")
Fixes: 3832b78b3ec2 ("dmaengine: at_hdmac: add missing put_device() call in at_dma_xlate()")
