ARM: hisi: handle of_iomap and fix missing of_node_put

Browse source

commit d396cb185c upstream.

Relying on an unchecked of_iomap() which can return NULL is problematic
here, an explicit check seems mandatory. Also the call to
of_find_compatible_node() returns a device node with refcount incremented
therefor an explicit of_node_put() is needed here.
