    clk: ti: dra7-atl: Fix reference leak in of_dra7_atl_clk_probe
    
    [ Upstream commit 9c59a01caba26ec06fefd6ca1f22d5fd1de57d63 ]
    
    pm_runtime_get_sync() will increment pm usage counter.
    Forgetting to putting operation will result in reference leak.
    Add missing pm_runtime_put_sync in some error paths.
