ARM: OMAP2+: Fix refcount leak in omap_gic_of_init

[ Upstream commit 0f83e6b4161617014017a694888dd8743f46f071 ]

The of_find_compatible_node() function returns a node pointer with
refcount incremented, We should use of_node_put() on it when done
Add the missing of_node_put() to release the refcount.
