[PATCH 1/2] cpuidle: dt: Add missing 'of_node_put()'

[Daniel Lezcano <daniel.lezcano@linaro.org>]

From: Christophe Jaillet <christophe.jaillet@wanadoo.fr>

'of_node_put()' should be called on pointer returned by
'of_parse_phandle()' when done. In this function this is done in all path
except this 'continue', so add it.

Fixes: 97735da074fd ("drivers: cpuidle: Add status property to ARM idle states")
