[PATCH] soc: bcm: brcmstb: Fix refcount leak in brcmstb_pm_probe

[Zheng Yongjun]

of_find_matching_node() returns a node pointer with refcount incremented,
we should use of_node_put() on it when not need anymore.
Add missing of_node_put() to avoid refcount leak.

Fixes: 0b741b8234c86 ("soc: bcm: brcmstb: Add support for S2/S3/S5 suspend states (ARM)")
