ARM: tegra: don't pass CPU ID to tegra_{set,clear}_cpu_in_lp2
tegra_{set,clear}_cpu_in_lp2 can easily determine which CPU ID they are running on; there is no need to pass the CPU ID into those functions. So, remove their CPU ID function parameter. Signed-off-by: Joseph Lo <josephl@nvidia.com> Signed-off-by: Stephen Warren <swarren@nvidia.com>
