This branch implements CPU hot-plugging support for both Tegra20 and
Tegra30. Portions of the implementation are contained in the clock
driver, hence this branch is based on the common clock conversion in
order to avoid duplicating work.

This branch is based on previous pull request tegra-for-3.7-common-clk.
