ARM: OMAP2+: Fix refcount leak in omap_gic_of_init
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.
Fixes: fd1c07861491 ("ARM: OMAP4: Fix the init code to have OMAP4460 errata available in DT build")
