[PATCH v3 8/9] ASoC: tegra: add clk_prepare/clk_unprepare

[Prashant Gaikwad]

Use clk_prepare/clk_unprepare as required by the generic clk framework.

Please ignore previous versions. Updated commit message and
maintainers properly in this version. No other change.

This patch should go through Tegra tree since other patches to port Tegra
to generic clock framework are dependent on it. Posting here to get ack from
the maintainers.
