[PATCH] soc: dove: add missing of_node_put before break

[Qing Wang <wangqing@vivo.com>]

From: Wang Qing <wangqing@vivo.com>

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

Early exits from for_each_available_child_of_node should decrement the
node reference counter.
