    powerpc/44x/fsp2: add missing of_node_put
    
    [ Upstream commit 290fe8aa69ef5c51c778c0bb33f8ef0181c769f5 ]
    
    Early exits from for_each_compatible_node() should decrement the
    node reference counter.  Reported by Coccinelle:
    
    ./arch/powerpc/platforms/44x/fsp2.c:206:1-25: WARNING: Function
    "for_each_compatible_node" should have of_node_put() before return
    around line 218.
