cpupfreq: tegra124: eliminate uses of of_node_put()
Make use of the __free() cleanup handler to automatically free nodes when they get out of scope. Only the probe function is affected by this modification. Given that this mechanism requires the node to be initialized, its initialization and the value check have been moved to the top of the function. After removing uses of of_node_put(), the jump to out_put_np is no longer necessary.
