ARM: hisi: check of_iomap and fix missing of_node_put
[ Upstream commit 81646a3d39ef14749301374a3a0b8311384cd412 ]
of_find_compatible_node() returns a device node with refcount incremented
and thus needs an explicit of_node_put(). Further relying on an unchecked
of_iomap() which can return NULL is problematic here, after all ctrl_base
is critical enough for hix5hd2_set_cpu() to call BUG() if not available
so a check seems mandated here.
