ARM: hisi: fix error handling and missing of_node_put
[ Upstream commit 9f30b5ae0585ca5234fe979294b8f897299dec99 ]
of_iomap() can return NULL which seems critical here and thus should be
explicitly flagged so that the cause of system halting can be understood.
As of_find_compatible_node() is returning a device node with refcount
incremented it must be explicitly decremented here.
