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.
