[PATCH] arch: powerpc: add missing of_node_put before break

[Qing Wang]

From: Wang Qing <wangq...@vivo.com>

Fix following coccicheck warning:
WARNING: Function "for_each_node_by_name" 
should have of_node_put() before return.

Early exits from for_each_node_by_name should decrement the
node reference counter.
