soc: qcom: smem_state: Add refcounting for the 'state->of_node'

Browse Source 
[ Upstream commit 90681f53b9381c23ff7762a3b13826d620c272de ]

In qcom_smem_state_register() and qcom_smem_state_release(), we
should better use of_node_get() and of_node_put() for the reference
creation and destruction of 'device_node'.
