[PATCH 4.9 039/191] clk: ti: composite: fix memory leak

[Sasha Levin]

From: Tero Kristo <t-kristo@xxxxxx>

[ Upstream commit c7c1cbbc9217ebb5601b88d138d4a5358548de9d ]

The parent_names is never released for a component clock definition,
causing some memory leak. Fix by releasing it once it is no longer
needed.
