clk: ti: dra7-atl: Fix reference leak in of_dra7_atl_clk_probe

Browse Source 
[ Upstream commit 9c59a01cab ]

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.

Fixes: 9ac33b0ce8 ("CLK: TI: Driver for DRA7 ATL (Audio Tracking Logic)")
