firmware: arm_scpi: add missing of_node_put after calling of_parse_phandle
of_node_put needs to be called when the device node which is got from of_parse_phandle has finished using it. Besides, of_address_to_resource always returns -EINVAL for error, delete the assignment for ret. Signed-off-by: Peter Chen <peter.chen@nxp.com> Signed-off-by: Sudeep Holla <sudeep.holla@arm.com>
