Subject: [PATCH 6/9] spi/tegra: add clk_prepare/clk_unprepare

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

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.
