amba: bus: fix refcount leak
[ Upstream commit e312cbdc11305568554a9e18a2ea5c2492c183f3 ]
commit 5de1540b7bc4 ("drivers/amba: create devices from device tree")
increases the refcount of of_node, but not releases it in
amba_device_release, so there is refcount leak. By using of_node_put
to avoid refcount leak.
