[ Upstream commit 8eb052f483 ]
npcm7xx_smp_boot_secondary() and npcm7xx_smp_prepare_cpus() look up
the GCR and SCU nodes with of_find_compatible_node(). The returned
nodes are used for of_iomap(), but the node references are never
released.
of_iomap() does not consume the device node reference, and iounmap()
only releases the MMIO mapping. Drop each node reference after the
corresponding mapping attempt.
